If you are getting table full error,may be your table
size is exceeding the maximum default size allowed.
check the table size and default size.
You can change the maximum size of the table using
Alter table command.
Somthing like following,but it is better so back up
the database before doing thi
there is no index
> on tableB.user_id your join will not work well,
> since the actual join

> Either change your index on table b to be
