Getting warning in DB2 stage
Posted: Fri Sep 30, 2011 2:32 am
Hi I am getting the below warning
"StageName": You have specified the query: `Query'
to run in parallel without using the NODENUMBER clause to localize the query;
this may result in extracting multiple copies of the answer set
leading to incorrect results and sub-optimal performance.
In the query where clause i am doing DBPARTITIONNUM(COLUMN_NAME) = CURRENT DBPARTITIONNUM
Please let me know the reason and solution for this....
