Try to replace all occurrences of $1 with $i. The problem occurs when assigning 0 to $1 in the for()-loop construct.

You cannot assign to $1 directly using the = operator - so from that point of view, $1 is read-only. $1 is usually set by a matching regular expression (capture), see also perlre.

Maybe, you should also increase your editors font size? ;-)

[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?
[atcroft]: abner: So you are wanting to do something like my $sth = $dbh->prepare(' SELECT * FROM charge WHERE col1 = ? and col2 = ?;'); $sth->execute(' asdf', 'asdw');?
