| Produkt: |
DB2 FOR LUW / DB2FORLUW / 950 - DB2 |
| Problembeschreibung: |
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:
