InsteadOF SQL

It is common in the database world (DB2 but all the others I have worked with are the same) to have a separate product installed that generates code and submits it to the database for processing. Eventually, you will encounter SQL that doesn't perform, as written by the product, yet could be made to perform quite well if it were re-written another way. I have encountered this situation a number of times myself.

Oracle has an interesting system where they can choose alternate execution plans for a piece of sql via baselines or profiles. However, if the fundamental sql is bad, there may be no fixing it with an alternate plan.

What I would like to see is a more sophisticated successor to Oracle's technology implemented in DB2, ie a companion to the existing INSTEAD OF TRIGGERS; INSTEAD OF SQL.

The name is fairly self-explanatory but, to be clear:

The engine:
1) analyzes incoming sql and generates a hashcode on the generic form of it (ie with place-holders for the actual values)
2) references a DBA-maintained table to see if said hashcode exists
3) if not, runs the orgininal sql
4) if so, does a replacement of variables into an alternate piece of sql supplied by the DBA (using the variables from the original)
5) runs the new statement INSTEAD OF the original and returns to the caller
