The first thing to do is create a database (aka Schema). Open MySQL Workbench and connect to your database server. From the database home screen. Linux: Launch by typing the command mysql-workbench. MySQL Workbench allows us to create tables, edit the attributes. On Linux, MySQL Workbench automatically added ananara.xyz extension, where an extension was not specified, to any script file saved from the SQL Editor. MySQL.

A listing of those items with their default values follows:. The Primary Key Column Name is the default primary key column name when using the table editor. Likewise with the default primary key data type, and column name and column type. The remaining items are the default names used when using the relationship tools on an EER diagram. For more information about these actions see Section Select whether to expand new objects by checking the Expand New Objects check box and select whether to draw line crossings by checking the Draw Line Crossings check box.
Use this tab to set the available colors for the objects that appear on an EER diagram canvas. You can also add colors if you wish. Changes made here affect the drop down list box of colors that appears on the toolbar when adding objects to an EER diagram canvas. For a discussion of using this list box see Section You can also use this tab to set the font face, font size, and the font style for the following list of items:.
Note that on Windows, the default font for the editor only supports latin-1 characters. If you need to use characters not supported by the latin-1 character set, you will need to change the font here. Before working directly with a live server a connection must be created. Once a connection is established it is the possible to execute SQL code directly on the server and manipulate the server using SQL code. Clicking this action item launches the Connect to Database Wizard.
From this wizard you can select a predefined connection. A new SQL Editor tab is launched where you. If you already have created a connection to a database it will appear in this panel as an icon. Double-clicking the icon will directly launch a SQL Editor tab, and connect you to the database as defined by the connection.
This wizard enables you to create a new connection. Note the wizard when launched from here does not display existing connections, it only enables you to create a new connection. To read more about creating and managing connections see Section This action item enables you to edit table data.
When clicked the Edit Table Data wizard is launched. This is a two stage wizard. The first stage enables you to select a Stored Connection. The second stage enables you to select the Schema and Table you want to edit. Once the wizard is completed a SQL Editor tab is launched which displays a data grid that enables you to interactively edit table data as required.
The second stage enables you to select a SQL Script file, and optionally have the script executed after it is opened. Once the wizard is completed a SQL Editor tab will be launched, with the script displayed. If you optionally selected to run the script, the script will run and the results will be displayed.
Clicking this action item launches the Manage DB Connections wizard. This wizard also displays Stored Connections, which can be selected to change as required. New connections can also be created from this wizard. To read more about managing connections see Section The connections created can then be used from the wizards that need to connect to a server, for example the wizard used to reverse engineer a live database.
However, it is still possible to set connection parameters from these wizards if required, without invoking the Manage DB Connections dialog directly. It can also be invoked from any of the wizards requiring access to a live database.
This is achieved by using the Manage Stored Connections item, found in the wizard's Stored Connection drop down list box. Once the Manage DB Connections dialog is launched, you are presented with a dialog that enables you to create or delete connections:. Click New to create a new connection. Once created the connection can be selected from the Stored Connections list. You can then set various parameters for the connection, including the following:. Connection Name : The name to use to refer to this connection.
This connection can then be selected from a dropdown listbox in other wizards requiring a connection. Once you have selected a connection method, the textfields available in the Parameters tab and the Advanced tab of the dialog will change accordingly. More details of these options and paramaters are avalable in the following sections. Once all parameters have been set as required you can click the Test Connection button to test the connection to the live server.
Once you are satisfied that the connection works as expected you can then close the wizard by clicking the Close button. You can then use the stored connection from any of the wizards requiring connection to a live server. You can also duplicate an existing connection using the Duplicate button.
Username : User account to use for the connection. Password : Optional password for the account used. If you do not enter a password here you will be prompted to enter the password for the account to be used when MySQL Workbench attempts to establish the connection.
MySQL Workbench also has the ability to store this password in a vault. On Linux, the vault is only implemented using the Gnome keyring facility - even on systems based on KDE. Default Schema : When the connection to the server is established this is the schema that will connected to by default.
There are also more parameters that can be set for the connection using the Advanced tab:. Use compression protocol : If checked, the communication between the application and the MySQL server will be compressed, which may increase transfer rates. This corresponds to starting a MySQL command-line tool with the --compress option. The client library needs to support this option. Note: this feature is currently not supported.
With this option enabled, you cannot use double quotation marks to quote literal strings, because it is interpreted as an identifier. Note: if this option is selected, it overrides the server setting. The name of the socket or pipe is entered here.
If the textfield is left blank the default socket or pipe name is used. This option was discussed in Section These are listed here:. An optional port number can also be provided. It is recommended that an SSH key file is also used. Note, only key files in OpenSSH format are currently supported. At this point you will be asked to select either a stored connection or enter the details for a new connection. Once a connection has been made to the server a new tab called SQL Editor schema is displayed:.
The Query item features the following menu items:. Explain All or Selection : Describes all statements, or the selected statement. Explain Current Statement : Describes the current statement. Stop : Stop execution of the currently running script.
Commit Transaction : Commits a database transaction. Rollback Transaction : Rolls back a database transaction. Refresh : Synchronizes with the live server and refreshes views such as the live Overview tabsheet. Commit Result Edits : Commits any changes you have made to the server.
Discard Result Edits : Discards any changes you have made. Export Results : This enables you to export result sets to a file. Selecting this option displays the Export Query Results to File dialog. Then click Export to export the data. The script will be displayed in the SQL Query area. Results are displayed in one or more Results tabs. Stop the query being executed : Halts execution of the currently executing SQL script.
This restarts the connection to the database server. Toggle whether execution of SQL script should continue after failed statements : If the red 'breakpoint' circle is displayed the script will finish on a statement that fails. If the button is depressed so that the green arrow is displayed, then execution will continue past the failed code, possibly generating additional result sets.
Any error generated from attempting to execute the faulty statement will be recorded in either case in the Output tabsheet. Commit : Commits a transaction. Rollback : Rolls back a transaction. Toggle Auto-Commit Mode : If selected, transactions will automatically be committed. For example, if a SQL script creates a new table, it will not appear in the Overview tab until the refresh toolbar button is pressed.
Toggle whether query result tabs should be kept between queries by default : Normally when a script is executed any results generated from previous executions of the script are lost, and the new results displayed in the results tab. If this toggle button is pressed, so that the pin appears inserted, results will be retained between executions. Each execution of the script will create a new Results tab containing the result set.
The statements entered can be saved to a file for later use. At any point you can also execute the statements you have entered. There is a quick way to enter the names of tables, views and columns. Simply double-click the item in the Schemata Palette and the name of the item clicked will be inserted into the SQL Query panel. This tabsheet provides an overview of the schema. The schema objects Tables, Views and Routines are displayed for the current schema.
The Output tabsheet displays a summary of the communication between the script and the server. The messages displayed can be information or errors. Each message displays the time, the action that was carried out, and the response from the server. This is useful for troubleshooting scripts. The History tabsheet provides a history of SQL operations carried out. At the time of saving you will be asked to specify a name.
The results area of the screen shows the results from any queries that have been executed. If the script contains multiple queries then multiple result tabs will be generated, one for each query that returns results. Controls are provided to allow you to easily move over the results. These are shown in the following screenshot:. There are a number of controls available. The controls from left to right are:.
Move to first row : Highlights the first record in the current result set. Move to previous row : Highlights the previous record. Move to next row : Highlights the next record. Move to last row : Highlights the last record in the current result set. Toggle wrapping of cell contents : The data in the cell can either be truncated or wrapped. This button enables you to toggle between these options. Sort Ascending : Sorts selected column in ascending order.
Sort Descending : Sorts column in descending order. Refresh Data from Data Source : Refreshes the current result set from the data source. Search for substring within data : Search data for the string entered in the search box. It is possible to edit data in real time using the Live Editing tabsheets.
In the Overview tab, if a table is double-clicked, a live editing tab will be launched, allowing you to edit the data maintained in that table. Field data can be edited by clicking a field and entering the required data, or editing existing data.
In addition to the controls offered by the Results tabsheet, the Live Editor tab features some additional controls. These controls are highlighted in the following screenshot:. Edit current row : Enters edit mode for the currently selected record. Insert new row : Inserts a new row and enables you to enter data. Your changes will not be reflected on the live server until you click Apply changes to data.
Delete selected rows : Removes the selected rows. Apply changes to data : Applies any changes that may have been made to the data fields to the live server. Discard changes to data : Discards any changes that may have been made to the data fields, and does not apply them to the live server. These additional controls allow you to apply or discard any changes you may have made to the field data.
If changes are applied, the data will then be synchronized with the live server. If changes are discarded the live server will not be affected. It is possible to enter a function, or other expression, into a field. This will ensure that the quoting is not escaped. See also Section The Object Browser contains a drop down listbox and a schemata explorer control. The drop down listbox lists the schema that are available on the currently connected server.
It is possible to select a schema to become the currently active schema using this facility. Once set, subsequent statements without schema qualifiers will be executed against this default schema. Note that this will only be set for the query session. If you wish to set a default schema for multiple MySQL Workbench sessions, you will need to set the default schema for the stored connection.
To do this from the Home screen click Manage Connections , then in the Manage DB Connection dialog set the desired default schema on the Parameters tab. This area enables you to explore the schemata available on the currently connected server. Double-clicking views, tables, and column names in the schemata explorer will insert the corresponding name into the SQL Query area.
This reduces typing significantly when entering SQL statements containing several tables, columns or views. The Object Browser also features a context menu which can be displayed by right-clicking, for example, a table. Right-clicking a table would display the following menu items:.
Select Rows - Limit : Pulls up to records of table data from the live server into a Results tabsheet. Edit Table Data : Pulls table data from the live server into a named tabsheet, and allows editing. Data can be saved directly to the live server. Copy to Clipboard : There are various sub-menus:. Alter Table : Displays the table editor loaded with the details of the table clicked on.
Create Table : Launches a dialog to allow you to create a new table. Drop Table : Drops a table. All data will be lost if this operation is carried out. Refresh All : Refreshes all schemata in the explorer by resynching with the server. Right-clicking an empty area inside the object browser displays the following menu options:. Create Schema : This enables you to create a new schema on the connected server. You can apply your changes to synchronize with the live server by clicking the Apply button.
Refresh All : Simply synchronizes with the live server so that information with the schemata explorer is updated. MySQL Workbench provides extensive capabilities for creating and manipulating database models. Some of these capabilities are listed here:. This is not an exhaustive list. These, and additional data modeling capablities, are discussed in the following sections. The Home screen is the typical starting point for work with data modeling. In the Data Modeling section of the Workspace you can use the action items there to create and manage models, forward and reverse engineer, and compare and synchronize schemata.
These action items are listed below:. Clicking this action item launches a file browser. You can then select the model file you wish to load. If you have already created one or more model files you can simply double-click the item of the model you wish to load. You can read more about modeling in the section Section Clicking this action item will launch a new MySQL Model tab, with a blank model ready for you to work on.
The purpose of this action item is to allow you to create an EER Model from an existing live database. Clicking this action item launches the Reverse Engineer Database. This is a multi-stage wizard that enables you to select a connection to a live server, and select the schema and objects you wish to reverse engineer into your new model. This is a convenient way to see how an existing database is structured.
For further information on reverse engineering see Section The purpose of this action item is to allow you to create a model from a SQL Create script. Such a script may have been created by hand or may be as a result of reverse engineering an existing database to generate the script, which may then be modified according to requirements. This is a multi-stage wizard that enables you to select the script you want to create your model from. The Sidebar is located on the left by default, but can be relocated to the right using a setting in the Workbench Preferences dialog.
For each of these sections objects can be added to a project by clicking the appropriate add object icon. You may also rename, edit, cut, copy, or delete objects on this page by right-clicking. Doing this opens a pop-up menu. Some menu options are not available in the OSS version of this application, and are only available in the Standard Edition.
This is indicated where applicable. Use this menu item to open a project, begin a new project, or save a project. Choosing New Model opens the default schema, mydb. The keyboard command to create a new project is Ctrl N and the command to open an existing project is Ctrl O. You can also do this from the keyboard by pressing Ctrl W.
When you save a model its name appears in the title bar of the application. If you have made changes to a project and have not saved those changes, an asterisk appears in the title bar following the model name.
If the script creates a database, a new tab bearing the database name is added to the Physical Schemata section of the MySQL Model page. If the script contains data, it will be ignored. Importing a DDL script is discussed in detail in Section Under the Import menu option you can also import DBDesigner4 files. There are variety of options under the Export menu item. You may generate the SQL statements necessary to create a new database or alter an existing one.
These menu items are discussed in detail in Section For an example of a PNG file see Figure The Page Setup menu item enables you to set the paper size, orientation and margins for printing purposes. The print options are only enabled if the EER Diagrams tab is selected. You have the choice of printing your model directly to your printer, printing it as a PDF file, or creating a PostScript file.
For more information see Section Use the Document Properties menu option to set the following properties of your project:. Created : Not editable, determined by the MWB file attributes. Description : A description of your project. Under this menu item find the options for cutting, copying, and pasting.
The Ctrl Z key combination can also be used to undo an operation. It is also possible to carry out a Redo operation using either the menu item, or the key combination Ctrl Y. The text description for this menu item changes to reflect the name of the currently selected object. The keyboard command for this action is Ctrl Delete. You can also right click an object and choose the delete option from the pop-up menu.
For instance, if an EER Diagram is active and a table on the canvas is the currently selected object, a dialog box may open asking whether you want to remove the table from the canvas only or from the database as well. If the MySQL Model page is active, the selected object will be deleted from the catalog and there will be no confirmation dialog box.
Choose Edit Selected to edit the currently selected object. You can also perform edits in a new window by selecting Edit Selected in New Window. Similar Figures Objects of the same type : Use this option to find objects similar to the currently selected object. Connected Figures : Use this option to find all the objects connected to the currently selected object. These menu items are only active when an EER Diagram tab is selected.
When multiple objects have been selected using one of these menu options, you can navigate between selected items by choosing the Go to Next Selected or Go to previous Selected menu options. Selecting items changes some of the Edit menu options. If only one object is selected, that object's name appears after the Cut , Copy and Delete menu options. If more than one object is selected, these menu items show the number of objects selected.
The Find menu item displays a sub-menu with the following menu items:. Find : Takes you to the toolbar search box. You can look for objects in the current view. Find Next : Finds the next occurrence of the object. Find Previous : Finds the previous occurrence of the object. Search and Replace : Displays the Search and Replace dialog.
This is currently only for use with the SQL Editor, to allow you to quickly search and replace script code items. Current View: Search the current view only. Selected Figures: Search the currently selected objects. This feature only works for EER diagrams. Enter the text you wish to search for in the Find Text drop down list box. You may also select any or all of the following check boxes:. Any text you enter into the Find Text drop down list box is retained for the duration of your session.
Use the Next or Previous buttons to find occurrences of your search criterion. Clicking the Find All button opens a Find Results window anchored at the bottom of the application. If you wish, you may undock this window as you would any other. Use this window to navigate to objects. For example, double clicking the Description of an object located on an EER diagram navigates to the specific diagram and selects the object. Notice that the properties of the object are displayed in the Properties palette.
The Find dialog window can also be opened using the Ctrl F key combination. Close the Find dialog window by clicking the x in the top right corner or by pressing the Esc key. Model Navigator : Open the Model Navigator palette. Catalog : Open the Catalog palette. Layers : Open the Layers palette. User Datatypes : Open the User Datatypes palette.

The keyboard shortcut for this menu item is Ctrl F2. For more information about the GRT shell see Section Reset Window Layout : Reset all windows to their default layout. The ability to zoom in on an EER diagram is also available using the slider tool in the Model Navigator palette. See Section Set Marker : Use this option to bookmark an object. From the keyboard select the object you wish to bookmark and use the key combination Ctrl Shift and the number of the marker 1 through 9.
You may create up to nine markers. Go To Marker : Return to a marker. From the keyboard use the Ctrl key and the number of the marker. The options under this menu item are as follows:. Align to Grid : Align items on the canvas to the grid lines. Bring to Front : Use this option to bring objects to the foreground. Send to Back : Use this option to move objects to the background. Center Diagram Contents : Use this option to center objects on the canvas. Autolayout : Use this option to automatically arrange objects on the canvas.
For example, if a table has a long column name that is not fully displayed, using this menu option will expand the table making the column visible. This menu item is not enabled until an object is selected. This option will display a table's columns if the object notation supports expansion. Some object notations, such as Classic , do not allow for expansion or contraction. Indexes will not automatically be expanded unless they were previously expanded and have been collapsed using the Collapse All menu option.
Collapse All : Undo the operation performed by Expand All. The menu options available under the Model menu item are as follows:. The keyboard shortcut is Ctrl T. DBDoc — Model Reporting Commercial version only. User Defined Types : Choosing this menu option presents you with a dialog box, allowing you to add and delete user defined data types. Object Notation : The items available under this option are discussed in Section Relationship Notation : The items available under this option are discussed in Section Diagram Properties and Size : Choosing this menu option opens a diagram size dialog box.
Use this dialog box to adjust the width or height of the canvas. The unit of measure is pages; the default value is two. When you have tables with numerous columns, use this menu option to increase the size of the EER. Validation : The items available under this option are discussed in Section Model Options : Set options at the model level.
These options should not be confused with the options that are set globally for the Workbench application, and which are now referred to as Workbench Preferences. The available model options are a subset of the Workbench Preferences options. For more information on Workbench Preferences see Section Use this dialog window to set the options for creating documentation of your database models.
Use these options for general validation and MySQL-specific validation of the objects and relationships defined in your model. Validate All : Perform all the validation options available. Empty Content Validation : Check for objects with no content, for example a table with no columns. Table Efficiency Validation : Check the efficiency of tables, for example a table with no primary key defined. Duplicate Identifiers Validation : Check for duplicate identifiers, for example two tables with the same name.
Consistency Validation : Check for consistent naming conventions. Logic Validation : Check, for example, that a foreign key does not reference a nonprimary key column in the source table. Integrity Validation : Check for invalid references, for example, a table name longer than the maximum allowed. Syntax validation : Check for correct SQL syntax. Duplicate Identifiers Validation Additions : Check for objects with the same name.
For detailed information about validation see Section They are grayed out if an EER diagram tab is not selected. Workbench Default : Display table columns, indexes, and triggers. Workbench Simplified : Show only a table's columns. Classic : Similar to the Workbench Simplified style showing only the table's columns. The object notation style that you choose persists for the duration of your MySQL Workbench session and is saved along with your model.
If you plan to export or print an EER diagram be sure to decide on a notation style first. Changing notation styles after objects have been placed on a diagram can significantly change the appearance of the diagram. The menu options are as follows:.
Crow's Foot IE : The default modeling style. For an example see Figure Classic : Uses a diamond shape to indicate cardinality. To view the different styles, set up a relationship between two or more tables and choose the different menu options.
The relationship notation style that you choose persists for the duration of your MySQL Workbench session and is saved along with your model. There are several options under the Database menu option:. Manage Connections : Launche the Manage DB Connections dialog, which enables you to create and manage multiple connections. Reverse Engineer : Create a model from an existing database. For more information, see Section Forward Engineer : Create a database from a model.
Synchronize Model : Synchronize your database model with an existing database. Generate Catalog Diff Report : Compare your schema model with a live database or a script file. Section The Plugins menu option lists any plugins that you may have installed. For more information about this menu option see Section Run Workbench Script : Executes the specified script. The Community menu option offers the following choices:. Read, search, or print the documentation from this window.
System Info : Information about your system, useful when reporting a bug. View Reported Bugs : Open your default browser to see a list of current bugs. Use the System Info menu option to determine information about your system. This option is especially useful for determining your rendering mode.
Sample output follows. The following tools always appear on the toolbar:. When an EER diagram canvas is selected, the following icons appear to the right of the arrow icons:. The toolbar also changes depending upon which tool from the vertical toolbar is active. These tools are discussed in Section If the Table tool is active, drop down list boxes of schemata, engine types and collations appear on the toolbar.
The table properties can then be modified using the Properties Editor. When an object is selected the object's properties, such as color, can be changed in the Properties Editor. When you add an EER diagram a new tab appears below the toolbar. Use this tab to navigate to the newly created EER diagram. EER Diagrams are discussed in depth in Section Expand and contract the Physical Schemata section by double-clicking the arrow on the left of the Physical Schemata title bar.
When the Physical Schemata section is expanded, all the schemata that are currently loaded are displayed. Each schema shows as a tab; a specific schema is selected by clicking its tab. There are a variety of ways to add schema to the Physical Schemata panel. To the left of these buttons are three buttons that control the way database object icons are displayed. The left-most button displays database objects as large icons, the next button to the right displays small icons in multiple rows, and the last button displays small icons in a single list.
The Physical Schemata panel is divided up into the following sections:. Each section contains the specified database objects and an icon used for creating additional objects. For information about adding objects to an EER diagram canvas see Section The Schema Privileges panel is divided up into the following sections:. To add a role, double-click the Add Role icon. Doing this creates a role with the default name role1.
Right-clicking a role opens a pop-up menu with the following options:. Edit in New Window : Open the role editor in a new editor window. To rename a role, simply click the role name and you will then be able to edit the text. All roles that have been defined are listed under Roles on the left side of the role editor. Double-clicking a role object opens the role editor docked at the bottom of the screen.
Select the role that you wish to add objects to. You may drag and drop objects from the Physical Schemata to the Objects section of the role editor. To assign privileges to a role select a role from the Roles section and then select an object in the Objects section. In the Privileges section check the rights you wish to assign to this role. Creating roles can make the process of assigning rights to new users much easier. To add a user double-click the Add User icon. Doing this creates a user with the default name user1.
Double-clicking this user opens the user editor docked at the bottom of the application. In the User Editor , set the user's name using the Name text box and set the password using the Password text box. Roles may be revoked by moving them in the opposite direction.
Right-clicking a user opens a pop-up menu. These options function as described in Section Use the Model Notes panel to write project notes. Any scripts or notes added will be saved with your project. Use the History palette to review the actions that you have taken. Left-clicking an entry opens a pop-up menu with the option, Copy History Entries to Clipboard.
Choose this option to select a single entry. You can select multiple contiguous entries by pressing the Shift key and clicking the entries you wish to copy. Select noncontiguous entries by using the Ctrl key. Docked at the top left of the application is the Model Navigator , or Bird's Eye panel. This panel gives you an overview of the objects placed on an EER diagram canvas and for this reason it is most useful when an EER diagram is active. Any objects that you have placed on the canvas should be visible in the navigator.
A black rectangular outline indicates the view port onto the visible area of the canvas. To change the view port of an EER diagram left click this black outline and drag it to the desired location. You can zoom in on selected areas of an EER diagram by using the slider tool at the bottom of this window.
The dimensions of the view port change as you zoom in and out. If the slider tool has the focus you can also zoom using the arrow keys. The default size of the Model Navigator is two pages. To change this use the Model , Diagram Size menu option. Doing this displays the following folder icons:. Selecting an object in this palette, displays its properties in the Properties palette, which can be found in the lower left corner of the screen.
On Linux, there is a quirk in the GTK tree control, where a simple click always generates a new selection. If you want to drag multiple objects from the Catalog Tree to the EER diagram canvas, you need to perform the operation as follows:. Hold shift and click last item and do not release the shift key.
Keep the shift key depressed and commence the dragging operation. Release the shift key before you release the mouse button to successfully drop selected objects onto the canvas. This also applies to use of the Ctrl key when selecting multiple non-adjacent elements in the Catalog Tree. You can toggle the sidebar on and off using the Toggle Sidebar button, which is located in the top right of the application. This palette shows all the layers and figures that have been placed on an EER diagram.
If a layer or figure is currently selected, an X appears beside the name of the object and its properties are displayed in the Properties palette. This can be especially useful in determining which objects are selected when you have selected multiple objects using the various options under the Select menu option. For more information on this topic see Section Selecting an object in the Layers palette also adjusts the view port to the area of the canvas where the object is located.
In some circumstances you may want to make an object on an EER diagram invisible. To do this, select the object and, in the Properties palette, set the visible property to False. The Layer palette provides an easy way to locate an object, such as a relationship, that has been set to hidden. Open the Layers palette and select the object by double-clicking it. You can then edit the object and change its visibility setting to Fully Visible. The Properties palette is used to display and edit the properties of objects on an EER diagram.
It is especially useful for editing display objects such as layers and notes. The color of the object is displayed here as is its hexadecimal value. Change the color of the object by changing this value. Only characters that are legal for hexadecimal values may be entered.
You can also change the color by clicking the This opens a color changer dialog box. A means of documenting the purpose of a layer. The value for this attribute is either true or false. It is currently only used for relationships. In addition to the properties listed above, tables also have the following properties:. For a discussion of the properties of connections see Section EER diagrams are created by double-clicking the Add Diagram icon. You may create any number of EER diagrams just as you may create any number of physical schemata.
Clicking an EER diagram tab navigates to the canvas used for graphically manipulating database objects. On the left side of this page is the Vertical Toolbar. The vertical toolbar shows on the left sidebar when an EER diagram tab is selected. The tools on this toolbar assist in creating EER diagrams. Clicking a tool changes the mouse pointer to a pointer that resembles the tool icon, indicating which tool is active.
These tools can also be activated from the keyboard by pressing the key associated with the tool. Locating the mouse over a toolbar icon displays a description of the tool and its shortcut key. The standard mouse pointer, located at the top of the vertical toolbar, is the default mouse pointer for your operating system. Use this tool to revert to the standard mouse pointer after using other tools. From the keyboard, use the Esc key to revert to the default pointer. The hand tool is used to move the entire EER diagram.
Left-click on this tool and then left-click anywhere on the EER diagram canvas holding down the mouse button. Moving the mouse changes the view port of the canvas. To determine your position on the canvas look at the Model Navigator panel on the upper right.
From the keyboard, use the H key to activate this tool. To do this see Section Change the mouse pointer to the eraser tool and click the object you wish to delete. Depending upon your settings, the delete dialog box should open, asking you to confirm the type of deletion. The delete action of the eraser tool is controlled by the general option setting for deletion. Be sure that you understand the available options described in Section From the keyboard, use the D key to activate this tool.
In addition to using the eraser tool, you can also delete an object by selecting it and pressing Ctrl Delete or right-clicking it and choosing Delete from the pop up menu. The layer tool is the rectangular icon with a capital L in the lower left corner. The layer tool is used to organize the objects on an EER Diagram canvas. It is useful for grouping together similar objects. You may, for instance, use it to group all your views together. Click the layer tool and use it to draw a rectangle on the canvas.
Change to the standard mouse pointer tool and pick up any objects you would like to place on the newly created layer. To change the size of a layer, first select it by clicking it. When a layer is selected small rectangles appear at each corner and in the middle of each side. Adjust the size by dragging any one of these rectangles.
You can also make changes to a layer by selecting the layer and changing properties in the Properties panel. Using the Properties panel is the only way to change the name of a layer. From the keyboard, use the L key to activate this tool. For more information about layers see Section The text tool is the square icon with a capital N in the top left corner.

Congratulations, you successfully created a database, added a table, and entered data into the table. Your database is ready to use.

Once you're done you should be able to remove the column without any issues.
Note: MySQL workbench cannot work without a primary key if that's your issue. However if you have a many to many table you can set both columns as primary keys which will let you edit the data. If you set a default schema for your DB Connection then Select will run in readonly mode until you set explicitly your schema.
