DB2 FOR LUW / DB2FORLUW / A50 - DB2

Under rare scenario, DB2 might produce non-optimal explain plan 
due to unoptimized predicates if the following conditions are 
true: 
1) The predicates are referencing one or more column organized 
tables 
2) The predicate has a correlated reference to column from 
another table 
3) The predicate is a relational operator of type >, >=, <, <=, 
<>, etc 
4) The outer column has another equality local predicate 
 
eg. Select * 
      from t1 
      where t1.c1 = 1 and 
                 t1.c2 = (select c2 from t2 where t1.c1 <= 
t2.c1);
