Re: error creating table
Hi Jim, Only difference is auto increment in the field. You cannot have two auto increment in a single table also auto increment field must be the key.

Then I redefined the primary keys in the parent tables to be the exact same type as the foreign keys in UserRole and it worked. So, check the datatype of all your keys and make sure they match.

Sorry, unrecognized username or password. Have you forgotten your password?
I have also posted this in drupal forum http://drupal.org/node/140303.
What I've done is I have exported data from old db via phpMyAdmin and
imported into new database.
Since it related to mysql so i'm posting here.
