Oracle-L: SQL*Loader - append to a table while checking column against another table

List,

I have been given a csv file to load into an Oracle table. This table has no referential integrity constraints (it is checked via the application) so I could end up inserting a bogus record.

Is there any way for me to check for the existence of a record in another table while loading data using SQL*Loader?

Here's the process I use right now:

Load records into a temporary table.
Query these records against the reference table. If record doesn't exist, spool it into a file, give it back to the BA, get them to fix it, then go through the whole process again until there are no bad records.

Seems like a roundabout way to do things - it definitely works for me but I just wonder if there is an easier way.

Thanks in advance,
Saira
