hok_si_la has asked for the wisdom of the Perl Monks concerning the following question:

Greetings Monks,

I use use DBI to execute my MS SQL server statements. I recently read Here that the method prepare_cached stores the statement handle in a hash associated with $dbh. What is the scope of that hash? Is it useless to use prepare_cached when a statement handle is not executed more than once within a given subroutine?

Thanks for your help

    The same as the $dbh. If a given statement is only executed prepared once on the same database handle, then prepared_cached is useless.

      I so mis-read that reply. Never mind.
