| Problembeschreibung: |
Under rare scenarios, if OLAP and aggregation functions are part
of the same expression in the select list,
DB2 might generate a SQL0901N error message.
eg. Select row_number() over () + min(c1) from t1;
SQL0901N The SQL statement failed because of a non-severe
system error.
Subsequent SQL statements can be processed. (Reason "Bad Opcode
