Granting rights to additional MySQL database causing issues

Question

I have a user \'myuser\' and two databases. \'db1\' and \'db2\'.

\'myuser\' already has rights to use db1

Answer 1

USAGE means "no privileges and that is what you have given your user when connecting from localhost.

I think localhost takes precedence over % so when the user is connecting from localhost that is the grant that will be used.

Grant access to both schemas to % (or localhost if that is what you prefer) and it should be clear and work better.
