Subject: SQL vs Native

I'm developing logic to create a "transactional" file/table in an existing RPG program that creates labels.
I'm trying to capture information about the labels we produce using a service program procedure and SQL.

The catch is that the users will, on occasion, recreate/reprint a set of labels. So I need to ensure I'm not creating duplicate transactions.

With native access, I would simply CHAIN then UPDATE or WRITE based on %FOUND.
With SQL, I would have to do a DELETE then INSERT for each record.
Just wondering if there's an alternative to the SQL method?

I'm trying to go 100% SQL for file access.

Thanks,
Greg
