RE: SQL Vs. RPG Opinions -- MIDRANGE-L

With CASE statements available now in SQL SELECT, lots of logic can be embedded in SQL statements. Although RUNSQLSTM does not allow SELECTs, it can do INSERT INTO TABLE VALUES(SELECT ....) and the logic could be there.

Or go with QMQRYs, which allow for replacement variables. And can run anything in SQL. Has outfile capabilities, etc. And outfile can *REPLACE contents of destination - dangerous, maybe, and very handy.

You COULD even generate the CSV directly, but the SQL gets messier with lots of concatenation and casting of data types. CPYTOIMPF is probably easier.

It will be something that will execute on a nightly basis. I'll be
refreshing the target database every night. Also, the logic is a bit
tricky.
