DB2 - Problem description

Problem IT17791 Status: Closed

SQL STATEMENT WITH AN EXISTS PREDICATE AND A JOIN INVOLVING
NON-DETERMINISTIC CORRELATED SUBQUERY MAY RETURN MORE ROWS

product:
DB2 FOR LUW / DB2FORLUW / 970 - DB2
Problem description:
Under rare circumstances, an SQL statement that satisfies all of
the following conditions may return more rows than expected:
(1) the query has a join between a table and a correlated
subquery that returns non-deterministic results (e.g. FFNR
clause without an ORDER BY clause, a non-deterministic function)
(2) the query has an EXISTS predicate
