Mysql_upgrade fails, table is corrupted I have a mariaDB with a table that is corrupted. It's useless data to me, so I've tried to drop the schema but it won't drop. Instead, it gives me this error when trying to drop it:

"Error Code: 1805. Column count of mysql.proc is wrong. Expected 20, found 21. The table is probably corrupted." 

I've read on here that I should try to run a mysql_upgrade to fix this issue. But this also has failed when I point to the MariaDB bin directory and run this command line:

C:\Program Files\MariaDB 10.2\bin&gt;mysql_upgrade --force -h localhost -uroot -p -
P3307


This is the results I get from it:

FATAL ERROR: Upgrade failed


Any advice on how to resolve this?
10.2.6 is a really old version from 2017, and the first table reelase..

Consider upgrading to latest 10.2 version (e.g. 10.2.25).

You table probably isn't corrupt, just has the wrong definition. In 10.2.6 it should look like this. Look to see what you need to alter to make this your table definition.
