I recently did a select on more than one table using DBI::MySQL, and the tables both had an "id" column.

So in my SQL I had to refer to them as table_a.id and table_b.id or whatever.

When I came to grab them from the hash as $ref->{'table_a.id'} and $ref->{'table_b.id'} I found they weren't there. There was just one $ref->{'id'}, so one had clobbered the other.

This didn't ruin my life, I just did it as an array instead, but it was frustrating. I imagined that DBD::MySQL would DWIM and it didn't.

I've had a quick glance at CPAN documentation and can't see it discussed. Any thoughts?
