The tab provides a detailed form for adding columns to the table and configuring table and column options. The tab also includes several of its own tabs near the bottom of the interface. Start by providing a name for the table. For this article, I used manufacturers. I also stuck with the default character set and collation, as well as the default storage engine, InnoDB.
The InnoDB engine is considered a good general-purpose storage engine that balances high reliability and high performance. Each one has specific characteristics and uses. For now, I recommend that you stick with the default InnoDB until you better understand the differences between storage engines.
I also recommend that you review the MySQL documentation for detailed information about the different engine types. Next, select the following check boxes:. If unsigned, the values cannot include negative numbers. Integer data types are signed by default. Integer signing affects the range of supported values.
Consider the INT data type. However, if the data type is unsigned, the values must be between 0 and If you know that a column will never need to store a negative integer, you can define the data type as unsigned to support a greater range of positive integers.
As you configure a column, Workbench updates the option settings in the section below the grid. This bottom section reflects the settings of the column selected in the grid and can be handy when defining multiple columns. The bottom section also provides several additional optional. For example, you can add a comment specific to the selected column.
You can also set the character set and collation at the column level for character data types. Notice that the bottom section reflects all the settings specified in the column grid. You can repeat a similar process for each additional column you want to include, choosing the data type and configurable options.
When specifying the data type, you can type it or select it from the drop-down list. This is apparently a Workbench bug. For this article, I added three more columns:. Figure 7 shows the Table tab after I added the three columns. In this case, I used , as shown in Figure 8. As you can see, there are plenty of other table options that you can configure, and there are other tabs on which you can configure additional options. On this screen, you can review the SQL statement that has been generated and select an algorithm and lock type, if desired.
You can also edit the SQL statement directly on this screen. Just be sure not to introduce any errors. To complete the table creation process, simply click Apply and then click Finish on the next screen. You should then be able to confirm in Navigator that the table has been created, as shown in Figure Notice that an index is created for the primary key column. Because a table can include only one primary key, there is no problem with duplicate index names.
They can also be useful when trying to understand the various options available when creating an object. With this in mind, the next step will be to create a second table in the travel database. The table is similar to the one I created in the first article in this series. It also shares some of the same elements as the manufacturers table you created above. In this way, you have more granular options for working with integer values.
The table definition also includes two table options. You can then view the table in Navigator, as shown in Figure As you can see, Navigator lists the foreign key beneath the Foreign Keys node. Notice that MySQL also adds an index for the foreign key, which is assigned the same name as the foreign key. This means that each column can store up to five digits with two decimal places. Each column definition also includes an AFTER clause, which specifies where to add the column in the table definition.
You can then view the new columns in Navigator. You can also use the Workbench GUI to alter a table definition. To do so, right-click the table in Navigator and then click Alter Table , which opens the Table tab. Here you can modify the column definitions or table options. You can also add or delete columns. The next step will be to add a generated column to the table. A generated column is one in which the value is computed from an expression, similar to computed columns in SQL Server and Oracle Database.
When you create a generated column in the GUI, Workbench automatically selects the Virtual option in the column detail area near the bottom of the tab. This means that the column values will be generated on demand, rather than being stored in the database.
The Stored option does just the opposite. The value is calculated when a row is inserted into the table, where the value remains until the row is updated or deleted. For this article, I used the Stored option. After you create a column, you can move it to a new location in the list of columns by dragging it to the desired position.
Here you can review the SQL script, as shown in Figure Figure Verifying the new column being added to the airplanes table. In addition, the clause includes the computed expression, in parentheses. Workbench also adds the STORED keyword to the column definition to indicate that the calculated values should be stored rather than computed on demand.
If this all looks good to you, click Apply again and then click Finish to close the wizard. Right clicking a row under the Column Name column opens a pop-up window with the following options:. Delete Selected Columns — Select multiple contiguous columns by right clicking and pressing the Shift key. Use the Ctrl key to select noncontiguous columns. Refresh — Update all information in the Columns tab. Clear Default — Clear the assigned default value.
Default " — Set the column default value to ". To change the name, data type, default value, or comment of a column, double click on the value you wish to change. The content then becomes editable. You can also add column comments to the Column Comment text area.
It is also possible to set the column collation, using the listbox in the Column Details panel. To the left of the column name is an icon that indicates whether the column is a member of the primary key. If the icon is a small key, that column belongs to the primary key, otherwise the icon is a blue diamond or a white diamond.
A blue diamond indicates the column has NN set. To add or remove a column from the primary key, double click on the icon. If you wish to create a composite primary key you can select multiple columns and check the PK checkbox. However, there is an additional step that is required, you will need to click the Indexes tab, then in the Index Columns panel you need to set the desired order of the primary keys.
For other data types the user must manage quoting if required, as it will not be handled automatically by MySQL Workbench. Care must be taken when entering a default value for non-numeric ENUM columns. When entering a non-numeric default value it will not be automatically quoted.
You must manually add single quote characters for the default value. Note that MySQL Workbench will not prevent you from entering the default value without the single quotes. If a non-numerical default value is entered without quotes, this will lead to errors. For example, if the model is reverse engineered, the script will contain unquoted default values for ENUM columns and will fail if an attempt is made to run the script on MySQL Server.
The Indexes tab holds all index information for your table. You can add, drop, and modify indexes using this tab. Select an index by right clicking it. Doing this displays information about the index in the Index Columns section. To add an index, click the last row in the index list.
Enter a name for the index and select the index type from the drop down list box. Select the column or columns that you wish to index by checking the column name in the Index Columns list. You can remove a column from the index by removing the check mark from the appropriate column. Create an index prefix by specifying a numeric value under the Length column.
You cannot enter a prefix value for fields that have a data type that does not support prefixing. To drop an index, right click the row of the index you wish to delete and then select the Delete Selected Indexes menu option. The Foreign Keys tab is organized in much the same fashion as the Indexes tab and adding or editing a foreign key is similar to adding or editing an index.
To add a foreign key, click the last row in the Foreign Key Name list. Enter a name for the foreign key and select the column or columns that you wish to index by checking the column name in the Column list. Under Foreign Key Options choose an action for the update and delete events.
To drop a foreign key, right click the row you wish to delete and then select the Delete Selected FKs menu option. To modify any of the properties of a foreign key, simply select it and make the desired changes. The Triggers tab opens a text area for editing an existing trigger or creating a new trigger. Create a trigger as you would from the command line. If you wish to enable partitioning for your table check the Enable Partitioning check box. Doing this enables the partitioning options.
The Partition By drop down list box displays the types of partitions you can create. These are:. Use the Parameters text box to define the parameter s that will be supplied to the partitioning function, an integer column value for example. Choose the number of partitions from the Partition Count drop down list box. If you wish to manually configure your partitions check the Manual check box. Doing this enables entry of values into the partition configuration table.
The entries in this table are:. Subpartitioning is not yet enabled. For more information about partitioning see Partitioning. The Options tab allows you to set the general options and row options. In the General Options frame, choose a pack keys option.
You may also encrypt the definition of a table. To set the row format, choose the desired row format from the drop-down list. When you expect a table to be particularly large, use the Avg. Row , Min. Rows , and Max. Rows options to enable the MySQL server to better accommodate your data.
The Storage Options section is used to configure a custom path to the table storage and data files. This option can help improve data integrity and server performance by locating different tables on different hard drives. You can also specify the action the server should take when users attempt to perform INSERT statements on the merge table.
You may also select the Merge Method by selecting from the drop down list box. Use the Inserts tab to insert records into the table. Clicking the Open Editor Use this editor to add records to the table. When you have finished adding records, press OK. The records you have added are displayed in the Inserts tab. Reopening the editor displays all the records shown in the Inserts tab.
To edit a record simply click on the field you wish to change and enter the new data. To delete a record, click the button on the left beside the desired row and then press the Delete key. You can select and delete all records by clicking in the top left hand column of the editor and then pressing the Delete key.
Your changes will not be applied until you press the OK button.
