SYMPTOMS
You may receive incorrect results, if your query meets the
following conditions:
- The query specifies a UNION or a UNION ALL of two or more
inputs.
- In the UNION, at least one of the SELECT statements return
the parameter or variable value (that is, it uses this value in the select list
and not in the where clause).
- The column returning the variable or parameter value is
being used as a join or grouping column higher in the query tree, and this
operator is run in parallel, requiring that the data stream be partitioned
based on the join or grouping columns.
The following query is an example of one that is subject to
this problem:
DECLARE @a SMALLINT
SET @a=1
SELECT yy, COUNT(*)
FROM (
SELECT productid xx, @a yy FROM products
UNION ALL
SELECT productid xx, unitsinstock yy FROM products
) zz
GROUP BY yy
Note This query is not a reproduce scenario for
the Northwind database. It is only there to show the form and syntax of a
hypothetical query on a hypothetical table named
products.
