Access denied to database even when privileges granted (3 replies)

Hi, I am using MySQL C++ connector 8.0 and while I connect to the database successful my program crashed saying access denied for user to the database. I have the user INSERT UPDATE DELETE AND SELECT privileges. At the time of the crash the program was inserting into the database. However I do a check to see if the table is locked before doing anything by running the query SHOW OPEN TABLES. But I believe I don't need superuser permissions for that? Or am I wrong? I logged into the mysql shell with the same user and can verify that I can insert into the database from there so I'm starting to think it could be the SHOW OPEN TABLES?

Thanks,
Eddy
