Error description
Under rare cases, DB2 might abend when the following conditions are true: 1) The query contains 3 or more left outer joins 2) The Join predicate in the top-most left join references a column from the null-producing side of the lowest left join. 3) The same column is also referenced in an equality predicate in an inner join e.g.: Select * from t1 left join t2 on t1.c1 = t2.c1 left join t3 on t1.c1 = t3.c1 inner join t4 on t2.c1 = t4.c1 left join t5 on t2.c1 = t5.c1
