Problem description: | |
A query can fail with with SQL0901, "Bad Plan; Unresolved QNC found". The conditions triggering the failure include a range partitioned table where applying some of the predicates, but not all predicates, will eliminate all partitions in a range partitioned table. The db2diag.log will contain the following message: 2010-03-18-11.24.10.716184-240 I624697E862 LEVEL: Severe PID : 23763 TID : 187955145056 PROC : db2sysc 1 INSTANCE: db2inst1 NODE : 001 DB : SAMPLE APPHDL : 1-32931 APPID: *LOCAL.db2inst1.10031516111 AUTHID : DB2INST1 EDUID : 151518 EDUNAME: db2agent (SAMPLE) 1 FUNCTION: DB2 UDB, relation data serv, sqlrr_dump_ffdc, probe:300 DATA #1 : SQLCA, PD_DB2_TYPE_SQLCA, 136 bytes sqlcaid : SQLCA sqlcabc: 136 sqlcode: -901 sqlerrml: 30 sqlerrmc: Bad Plan; Unresolved QNC found sqlerrp : SQLNG006 sqlerrd : (1) 0x00000000 (2) 0x00000000 (3) 0x00000000 (4) 0x00000001 (5) 0xFFFFFFCE (6) 0x00000001 sqlwarn : (1) (2) (3) (4) (5) (6) (7) (8) (9) (10) (11) sqlstate: | |
