Cause

'stash.HT_sta_pr_activity' is not a table created by Stash.

As per this blog, this behaviour is related to temporary tables Hibernate creates (or is supposed to create) for some operations around the inheritance hierarchy for activity tables. That suggests that the user Stash is using to connect to MySQL does not have the right permissions. Specifically, from MySQL's reference:

Temporary Tables

You can use the TEMPORARY keyword when creating a table. A TEMPORARY table is visible only to the current connection, and is dropped automatically when the connection is closed. This means that two different connections can use the same temporary table name without conflicting with each other or with an existing non-TEMPORARY table of the same name. (The existing table is hidden until the temporary table is dropped.) To create temporary tables, you must have the CREATE TEMPORARY TABLES privilege.

Further Troubleshooting

Use the Show Grants command to confirm the permissions for the Stash user and ensure they have the CREATE TEMPORARY TABLES permission on the Stash database.

Resolution

To create temporary tables, you must have the CREATE TEMPORARY TABLES privilege. Ensure 'GRANT ALL PRIVILEGES' has been used when creating the Stash database as mentioned in the MySQL setup guide.
