After installing the SQL Sandbox application, you must grant the DML role to a user in order to be able to access the application.

Open the application in the browser. The application allows you to execute any SQL statement directly on the platform database, and displays the results in a tabular view similar to an aggregate preview. Note that the SQL statement must use the physical table names, which you can lookup using the Entities side panel.

Take extreme caution when executing INSERT, UPDATE and DELETE statements, as they may possibly corrupt data and even cause the OutSystems platform to malfunction beyond repair.
