Why? The SQL never changes, so you're just using up memory for nothing.

Sorry, should have posted the error. I'm guessing that according to SQLite, the SQL does change. My prepared_cached statement goes from:

UPDATE twsJobs SET command = ? WHERE jobId = ?";

to:

UPDATE twsJobs SET ? = ? WHERE jobId = ?";

and the error I receive is:

DBD::SQLite::db prepare_cached failed: near "?": syntax error at...

Evidently, by changing the column name SQLite feels I'm altering the SQL and therefore I get the error with placeholders. By placing the column name in place of the 1st ?, the SQL runs fine. If I can't have a placeholder for the column names, I need to generate the SQL statement each time. I'm hoping some monk may be able to give me insight into how to have a placeholder for the column name.
