Clicking this action item launches the Edit SQL Script wizard. This is a two-stage wizard. The first stage enables you to select a Stored Connection. The second stage enables you to select an SQL Script file, and optionally have the script executed after it is opened. After the wizard is completed, an SQL Editor tab will be launched, with the script displayed. If you selected to run the script, MySQL Workbench runs the script and displays the results.
The Edit SQL Script wizard is not well-suited for executing large dump files, and instead the Server Administration, Manage Import/Export feature should be used.
