Hello,
Thank you for your MySQL WorkBench question. I am not quite understanding the question. Does MySQL WorkBench keep a list of all previous queries run? Have you tried with another program such as HeidiSQL? If the behavior only occurs with MySQL WorkBench then this would be a client-side issue and not a server one, so you may want to check with MySQL WorkBench support forums for the proper functionality of the software.
Kindest Regards,
Scott M
