DB2 - Problem description
| Problem IC69434 | Status: Closed |
THERE COULD BE -901 WHEN COMPILING A QUERY CONTAINING SCALAR AGGREGATE FUNCTIONS WITH PARTITION BY CLAUSE IN SMP | |
| product: | |
DB2 FOR LUW / DB2FORLUW / 980 - DB2 | |
| Problem description: | |
In SMP environment(ie. intra-partition parallelism is enabled),
if a query containing scalar aggregate functions with PARTITION
BY clause, eg. ROWNUMBER() OVER (PARTITION by
A.APLY_NO,A.POLICY_NO), then there could be -901 error
happening.
An error message may be left in db2diag.log looked like this:
