Load Spatial Data : Imports a shapefile. A new table with the imported fields is created in the selected schema, unless you select the append or update overwrite option. Another option creates a spatial index. If enabled, the import operation makes a spatial index around the geometry column. You can import spatial data with or without an EPSG format conversion.
Set as Default Schema : Sets the selected schema as the default schema. This setting applies only to the query session. To set a default schema for multiple MySQL Workbench sessions, you must set the default schema for the stored connection. The selected schema is displayed as bold in the schema navigator. Filter to This Schema : Enables you to target specific schemas in the list.
Schema Inspector : Displays information about the selected schema. For additional information, see Schema Inspector. Table Data Import Wizard : Opens the wizard. Create Schema : Launches a dialog to enable you to create a new schema. Drop Schema : Drops the schema. All data is lost if this operation is carried out.
Search Table Data : Opens a new tab for performing table searches. It performs a search on all columns, and offers additional options to limit the search. Refresh All : Refreshes all objects in the schema tree by resynchronizing with the server. Double-clicking a table, view, or column name in the schema explorer inserts the name into the SQL Query area. This reduces typing significantly when entering SQL statements containing references to several tables, views, or columns.
Table, view, and column context menus. The schema navigator also features a context menu, which can be displayed by right-clicking a table, view, or column object. For example, right-clicking a table displays the following menu items:. Select Rows - Limit : Pulls up to rows of table data from the live server into a Results tab, and enables editing.
Data can be saved directly to the live server. Table Inspector : Displays table information, similar to the Schema Inspector. This also has a simpler and easier to use interface for analyzing and creating indexes for tables. Copy to Clipboard : There are various submenus, each of which copies information to the clipboard. Name short : Copies the table name. Select All Statement : Copies a statement to select all columns in this form. Type the password when prompted and press Enter.
Note: If you're getting an access denied error, follow our troubleshooting guide: Access denied for user [email protected]. All the outputs show the size in MB with two decimal places. The output sorts the tables by size in descending order in MB. The query sorts the output by database size. Change the last line to sort by a different parameter.
However, the program provides two additional ways to quickly check the size of a single database and the tables inside a database. To get the size of a single database in MySQL Workbench, right-click on the schema you want to check in the left navigation pane. Select Schema Inspector from the list. On the right pane, under the Index tab, check the database size. Check the size of a specific table in the Data Length column or add them together to get the total amount.
InnoDB maximum size for tables is TB, which corresponds to the full tablespace size. Generally, the best practice is to divide an InnoDB table into multiple tablespaces. Depending on the specifications, some operating systems limit the file size. Although MySQL has some table size limits, a full table error is most likely due to the operating system. Alternatively, the storage where the database resides is possibly at full capacity.
You should now know several methods to get database and table sizes after following this tutorial. Introduction MySQL provides valuable metadata about databases and tables. Was this article helpful?

MySQL Workbench simplifies database design and maintenance, automates time-consuming and error-prone tasks, and improves communication among DBA and developer teams. It enables data architects to visualize requirements, communicate with stakeholders, and resolve design issues before a major investment of time and resources is made. It enables model-driven database design, which is the most efficient methodology for creating valid and well-performing databases, while providing the flexibility to respond to evolving business requirements.
Model and Schema Validation utilities enforce best practice standards for data modeling, also enforce MySQL-specific physical design standards so no mistakes are made when building new ER diagrams or generating physical MySQL databases. MySQL Workbench provides capabilities for forward engineering of physical database designs.
A visual data model can easily be transformed into a physical database on a target MySQL Server with just a few mouse clicks. You can find the EER diagram workbench file created in this tutorial on Github. The visual database model created can be transformed into a physical database. This process is known as forward engineering. This is easier than writing the code manually.
Select the objects you would like to include in the EER diagram. These will include tables, views, routines, users, and triggers. In this exercise, we only have tables. In this step, we are provided with the generated SQL script. Find the SQL file generated in this tutorial on Github.
This is the final step. Click finish to commit. The database created will be as shown in the screenshot below. Reverse engineering enables us to have a better view of an existing database. A physical database is converted to an EER diagram. We will be reverse engineering the database we created earlier. In this tutorial, we will use the live database we created in the forward engineering section. Create a new connection to the MySQL Server or select an existing one, as shown in the screenshot below.
Review the information displayed and make sure that the connection was successful, then click NEXT. Select the schema you would like to reverse engineer. In this case, select booksdb , then click NEXT. The results of the tasks carried out are displayed in the wizard below. Review the results, then click NEXT. We are prompted to select the objects to reverse engineer.
By default, all the available objects are selected. Leave the default options, then click NEXT. The wizard shows the reverse engineering progress. In the screenshot below, the process was successful. In case of an error, check error details by clicking Show Logs. MySQL Workbench is such a useful tool. It can be used by MySQL database administrators, system developers, and database developers. At first, the tool may seem complex to use, but with time it gets easier. Practice makes perfect.
In this tutorial, the focus will be on database design. You can do this from the installation wizard. Linux: Launch by typing the command mysql-workbench. Provide the connection details. The created connection will be displayed, as shown in the screenshot below. After adding a new diagram, a new window will be opened, as in the screenshot below.
Scenario In this tutorial, we will model and create a database that will be used to keep book details. Publisher: id, name. An author can have multiple publications. A book can also have multiple authors. This type of relationship requires an extra table called a bridge table. MySQL Workbench automatically creates a bridge table when we add a many-to-many relationship. The relationship between the book and the publisher is one-to-many. A book can only have one publisher. A publisher can publish multiple books.
The vertical toolbar panel The vertical toolbar has different tools used in creating EER diagrams. Add tables We are going to add three tables to the EER model. To add a table, follow these steps: Select the table tool on the vertical tools panel, then click anywhere on the EER diagram canvas.
This creates a table with no columns. Double click the table created to open the table properties window. On the table properties window, change the table name. Add columns to the table. To add new columns, click on the last blank column. Edit the column name and select the appropriate data type for each column.
Please do not add the columns described as foreign keys. MySQL Workbench has an easier way of adding them by creating relationships, and the foreign keys are added automatically. Select all the column properties such as primary key, not null, unique, and autoincrement. Repeat the process for all the tables. Your EER diagram should look as shown below.
Add relationships We will add two different relationships to the EER diagram. One-to-many relationship There is a one-to-many relationship between the book and the publisher.
