Problem IT04161 Status: Geschlossen

DB2 MIGHT ABEND WHEN EXECUTING QUERY CONTAINING A SUBSELECT WITH REDUNDANT
PREDICATES

Produkt:

conditions are true: 
 
1) The query contains one or more subqueries. The subquery can 
be of the form EXISTS, NOT EXISTS, etc. 
2) The subquery contains one or more correlated predicates 
3) Atleast one of the correlated predicate in the subquery can 
be proven to be redundant due to a check constraint, tautology 
predicates, etc.
