i followed below steps to have Autocommit checkbox in SQL Workshop → SQL Commands so i can turn off Autocommit to avoid any loss.
Login as Administrator ( Internal Workspace ) -my local VM-
Go to Manage Instance → Feature Configuration → SQL Workshop → Set Enable Transactional SQL Commands to Yes then Apply Changes
now login as developer/normal user
goto SQL Workshop => SQL Commands
you should see a checkbox with label Autocommit, check/uncheck it and test.
i UnCheck the checkbox before label Autocommit and tested DML as in screenshot below, it didn't worked. how i can do this?

regards
