Exactly! This is the thing that ora_check_sql=>0 prevents when you use the Perl DBI. Then there's the problem of doing the prepare() inside a loop. The way to fix that problem is to NEVER PARSE INSIDE A LOOP.

They often do a describe before a parse, which results in two parses for every execution. 945 * 2 = 1895 Josh -----Original Message----- Sent: Wednesday, August 20, 2003 1:34 PM To: Multiple recipients of list ORACLE-L Why should a query such as this, with bind variables and no literals, be parsed so many times? Other queries in the trace show, for example, 2 parses and 160000 executions. And while I'm at it, why does is the parse count shown equal to the SUM of executes and fetches?
