Problembeschreibung: | |
To hit the problem, a query needs satisfy all the following characteristics: (1) Query has UNION ALL or LEFT OUTER JOIN construct. (2) Query has ORDER BY clause applied on the result of UNION ALL or LEFT OUTER JOIN (3) At least two columns in ORDER BY clause are equivalent. (4) The Fetch First N rows clause is used. The problem symptom is one of two SQL0901N errors: SQL0901N The SQL statement failed because of a non-severe system error. Subsequent SQL statements can be processed. (Reason "this->qclqclord.pp() != NULL".) SQLSTATE=58004 or SQL0901N The SQL statement failed because of a non-severe system error. Subsequent SQL statements can be processed. (Reason "sqlno_int_order_opr_req [400]:rc(-2144272209) Sibling order r".) SQLSTATE=58004 An example query is select * from table (select * from t1 union all select * from t2) where c1 = 1 and c2 = 2 and c3 = 1 and c4 = 4 order by c1, c2, c3, c4 fetch first row only; | |
