Subj:   Re: Derived tables on V2R5
 
From:   Meade, Cornelius

I would have to say that without qualifying the "tool" in question that it depends....Derived tables certainly have had use in the past as a means to guide the RDBMS to what often was a more efficient execution plan in certain situations. Teradata is not unique in that vein and that really is a execution/performance question. Hopefully that type of use will be come a moot issue as the optimizer is made more intelligent per Fred's comments about NCR intentions in that area (and that will truly be a glorious day!). Beyond that however I think of "derived tables" from a SQL syntax/coding standpoint. In that vein, they serve many useful purposes and I think they have entered the SQL lexicon permanently and are here to stay....
