in reply to comparing multiple lines in an array.

There's some good stuff about pulling out duplicate elements in an array here - you could probably adapt any of these solutions for your case, perhaps by using a hash of hashes of hashes.

[atcroft]: abner: Do you mean something like SELECT `foo`, `bar` FROM `table_name' WHERE (( `foo` = "asdf" ) OR ( `bar` = 'asdw' )); Or something else?
[abner]: yes. i am familiar with mysql but ignorant about how to get around the fact that placeholders can only represent single scalar values.
[abner]: my $sth = $dbh->prepare(' SELECT * FROM charge WHERE cpt = ?') or die "Couldn't prepare statement: " . $dbh->errstr;
[abner]: what if i want SELECT * FROM charge WHERE col1 = x and col2 = y?
