Problem description: | |
Compiling a query on DB2 v9.7 fix pack 1 may result in the DB2 instance terminating abnormally with a stack similar to this example from Linux: 0000002A9AE8F0BE ossDumpStackTrace + 0x0186 0000002A9AE8CBD4 _ZN11OSSTrapFile4dumpEmiP7siginfoPv + 0x00aa 0000002A97F4A8DF sqlo_trce + 0x03cf 0000002A96D94B78 sqloEDUCodeTrapHandler + 0x02b8 0000003130A0C5B0 address: 0x0000003130A0C5B0 ; dladdress: 0x0000003130A00000 ; 0000002A965D4FB9 _Z21sqlnq_const_fold_treeP9sqlnq_pidRbP3loc + 0x0171 Another possible symptom of this problem is SQLCODE -901 with one of the two following reason codes: SQL0901N The SQL statement failed because of a non-severe system error. Subsequent SQL statements can be processed. (Reason "invalid qnc assigment".) SQLSTATE=58004 or SQL0901N The SQL statement failed because of a non-severe system error. Subsequent SQL statements can be processed. (Reason "column number out of range".) SQLSTATE=58004 To hit this problem, a query must have an outer join whose result is inner joined with a base table and there must be a join predicate, for example: create view V as select * from T1 left outer join T2 ... select * from V, T3 where V.C1=T3.C2 The problem only occurs on DB2 v9.7 fix pack 1. | |
