In private communication with Cary Millsap, I was warned about the
undocumented DBI handle attribute called "ora_check_sql" which was
defaults to "1" and, oracle versions 8 and above, causes oracle to
parse each statement twice ($sth=$dbh->prepare() is the first parse
and 4sth->execute() was the second). On 1/27/2004. Tim Bunce delivered
the new DBD::Oracle v1.15 and in the documentation one can find the
following text:
***************************************************************************
ora_check_sql
If 1 (default), force SELECT statements to be described in prepare
(). If 0, allow SELECT statements to defer describe until execute().
(OCI8 and later only.)
See "Prepare postponed till execute" for more information.
**************************************************************************
When I did the unthinkable and read the documentation (I know, real DBA
is not supposed to read the documentation, but learn by osmosis) I
remembered the correspondence with Cary and decided to publish it for
the rest of the good, hard hacking, perl folks.
