In the case in question, there was no need to get the actual data, the only question was if there were any rows returned.

In that case you could do with a different approach -

my $sql = "SELECT count(*) FROM table WHERE .... ";

This query will return a single row containing the count of matching rows (row count) in the table. I believe this is the most efficient and portable way to determine the number of rows, and the fastest too.
