DB2 FOR LUW / DB2FORLUW / A50 - DB2

Under rare scenarios, DB2 might produce incorrect result when 
the following conditions are true: 
1) The query contains one or more correlated scalar subqueries 
2) The scalar subquery has an aggregation function of type 
MAX/MIN 
3) The table referenced in the subquery is also joined to the 
parent of the correlation in the outer select 
4) The join predicates of the 1 and 2 are identical 
 
Eg. 
SELECT * 
FROM  tab1 d , tab2 c 
where d.c1 = c.c1 
and c.c1 = 
       ( SELECT MAX(c1) 
         FROM tab2 catg 
         WHERE catg.c1 = d.c1 );
