And what is the SQL? Maybe a Cartesian product has slipped in.

And in all likelihood, that would be the wrong road.

The high level suggestion is to produce a standalone example cut down to
the bare minimum necessary to reproduce the problem. Start from scratch,
which means an empty file, and then strict and warnings. And in your
case, the DBI, then the connect, then your statement, prepare, and
execute. It is very common to discover, in the process of doing so, the
source of the error, typically in one's own code.
