Not sure if it's faster, but you could always try not using placeholders:

my $sql = sprintf q[ SELECT * FROM my_table WHERE col_1 IN (%s) AND col_2 IN (%s) ], join(', ', @$set_1), join(', ', @$set_2);

If you can't be sure that they are all integers, be sure to map then through $dbh->quote first.

Use:  <p> text here (a paragraph) </p>

  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
  • Please read these before you post! —
