Commit and Rollback Statement in SQL
Thanks for reaching out!
Can you please verify whether you have "un-ticked" the Safe Updates option from the Edit/Preferences/SQL Editor window?
After you've done that, please reconnect to the database by pressing this icon. Finally, if this doesn't help, you can restart Workbench.
Hope this helps but please feel free to get back to us (with additional information, please) should you need further assistance. Thank you.
