After the delete command, I tried using the rollback operation but it does not seem to be working.

Hi Ajayi! Thanks for reaching out. In the Workbench, there is the possibility to toggle the autocommit mode by pressing a single button. If you have pressed the tenth icon from left to right on the same line with the lightning symbol, that mode will be turned on, and each statement will be committed immediately. So, please press it and then use the ROLLBACK command. Hope this helps. Best, Tsvetelin
