DB2 FOR LUW / DB2FORLUW / A50 - DB2

An outer join query may return incorrect results when all of the 
following conditions are satisfied: 
- The registry variable DB2COMPOPT is set to list that includes 
OJLOCALPRDPLANNING either explicitly or implicitly by setting 
the DB2_WORKLOAD registry variable to 1C or PUREDATA_OLAP 
- There is a predicate in the ON clause of the JOIN operator 
that references only columns from the row preserving side of the 
join operands 
- The access plan of the query has a partial GROUP BY operator 
on the row preserving operand of the outer join operator
