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 "Parallelism" in the execution plan output; the following sample code illustrates this point:
|--Parallelism(Repartition Streams, PARTITION COLUMNS:([fvs].[FileID]))
