SYMPTOMS
A SELECT statement that performs parallel logical operations may return a number of rows that is not consistent. View the execution plan to determine if the query is running in parallel. To obtain the execution plan, run SET SHOWPLAN_TEXT ON in a separate batch before the query. For example: USE pubs

GO

SET SHOWPLAN_TEXT ON

GO

SELECT * FROM authors

GO A parallel plan contains the word &quot;Parallelism&quot; in the execution plan output; the following sample code illustrates this point: |--Parallelism(Repartition Streams, PARTITION COLUMNS:([fvs].[FileID]))
