Your dienice() doesn't actually print anything, it returns a string, but you're not using the return value in any way...

Is there a reason you're connecting to a database in every iteration of your loop? That's probably going to be slow. Is there a live database connection at the beginning of the loop? Prepare all your SQL statements OUTSIDE of the loop with separate statement handles, and just execute them INSIDE the loop. Except for the CLASSES_RECORD insert statement, then maybe you could use 'prepare_cached'...

You CAN use placeholders/bind values ('?') even in the insert statements, you know.

Also, set RaiseError at least while testing. See 'perldoc DBI'.

And last, have you tried running it in the debugger?
