For example:
EXPLAIN ALL SET QUERYNO = 1 FOR
SELECT C1,C2 FROM T1
WHERE T1.C1 = 100;
Index IX(C1) is chosen to access T1. When populating data into
PLAN_TABLE, an invalid array index zero is used that may result
in ABEND0C4 at DSNXOD3 offset 04726 or incorrect information in
column IBM_SERVICE_DATA of PLAN_TABLE.
Problem conclusion
Db2 has been modified to correctly process the aforementioned
SQL statement.
