Problembeschreibung: | |
A query with nodenumber/dbpartitionnum scalar function might return incorrect results. The query may fail to collect rows from specified database partition(s) if all the following conditions are met: 1. The query involves a UNION (could also be via view with union or full outer join which the compiler will generate a union for) 2. At least one branch below the UNION applies a NODENUMBER or DBPARTITIONNUM function 3. There is a DTQ below the UNION (in db2exfmt output), and the details of the DTQ in the db2exfmt output shows the following: Output Streams: -------------- ... Partitioning: (FUNC ) NODENUMBER() or PARTITION() directed to Single Partition ... Partition Column Names: ---------------------- +NONE | |
