I don't see how Oracle could ever have an official position on hints. If
they say hints are going away, many developers panic. If they say hints are
great, then Oracle competitors will claim Oracle has a bad optimizer.

A key political issue in some shops is "Using hints makes our code Oracle-specific". My reply is that hints are only comments that another database will ignore.

Hi,

I have to write a SQL and PL/SQL guide for our developpers. Some are good but most of them can use help.

I'm not a big fan of hints except for insert append, I used them only if I
really need to.

In last october I went to a 3 days DB2 UDB course, unless I miss something
there are no hint with DB2 UDB.
So I was thinking that when the Oracle optimiser would be more mature maybe
hints would go away.

I just want to know what is Oracle direction with hints.

TIA Stephane

This is facinating, where does this come from? This is the second time in a
week that I've heard this statement being made by someone. Hints will never
go away IMHO, and Oracle continues to add more and more of them. I was told
by someone at a client site that they were told by an Oracle instructor that
they should not use hints in 9i....

Hi,

Does Oracle have an official position on hints ? Will they go away as the optimiser is becoming bettre or they are there to stay ?
