DB2 FOR LUW / DB2FORLUW / A50 - DB2

This enhancement improves DB2 performance when the following 
conditions are true: 
1) The SQL query is either SELECT,UPDATE or DELETE 
2) The query references column organized tables 
3) The query contains one or more correlated scalar subqueries 
4) The correlated predicates are equality join predicates 
5) There does not exist any primary or unique key across all the 
predicate columns 
 
eg. 
Select * 
From T1 
Where T1.C1 = 1 and T1.C2 = (Select max(c2) from T2 where T1.c3 
= T2.c3);
