Hi Glenn, I was wondering if you had an example of what you meant by your derived table problem.
I have interpreted what you have said to mean that one of the following will fail on V2R5. And yet I have tried both queries on two V2R5 systems (a beta version and a GCA version) and both queries appear to work on both systems.
Also I am interested in the sorts of performance issues you had. Initial impressions are that our applications appear to run a whole lot faster on V2R5 than V2R4.0.3 and V2R4.1.3.
Multiload session establishment seems to be significantly faster on V2R5 (we haven't done large volumes of data yet - so can't make a real comment on overall mload performance)!
Is this what you mean by unspecified columns in the select?
select * from ( select * from ( select * from x ) as dt_x ) as dt_x ;
All columns specified
select c1 from ( select c1 from ( select c1 from x ) as dt_x (c1) ) as dt_x (c1)
