$sth->execute or die "Cant execute ($stmt) - $DBI::errstr\n";
This is the proper way to do it (checking the return value of execute) - not the one you quoted at the top (checking errstr).

I don't know if your problem is related but I remember a problem I once had with DB2 where a prepare using a non-existing column did not fail and it turned out that the DB2-client was configured in such a way that no data was sent to the server before the execute.

The DB2 client is highly configurable to minimize database-roundtrips and that sometimes means that errors are detected later then you would assume.

In your script it seems the only thing that fails is the first fetch and maybe this is again the first time data is sent to the server.

Try to talk to your admin or trace your session.
