You can use MySQL Workbench to run a query, then export the results of that query to a file.
To do this:
- Run the query
- Click Export on the Results Grid menu bar
You can save a query result to a .CSV file by using the
SELECT ... INTO OUTFILE statement.
You specify the name/location of the file as well as other options, such as field terminators, line terminators, etc.
To create a relationship in MySQL Workbench:
- Create a database model (either create a new model or reverse engineer an existing database)
- Viewing the database model, double click on the first table of the relationship
- The bottom pane will open with the table details. Click on the Foreign Keys tab
- In the left pane, select the foreign key field and referenced table
- In the middle pane, select the foreign column and referenced (primary key) column
- In the right pane, set any Update/Delete actions you’d like to occur when a primary key record is updated or deleted
The relationship is now established. Repeat steps 4 to 6 for any other foreign key columns in that table.

- The wizard will retrieve all objects from the selected schema/s and check the results. Click Continue
- Select the database objects you’d like to have reverse engineered, then click Execute
