BUG #: 355092 (SHILOH_BUGS)



SYMPTOMS
SQL Server ignores the ORDER BY clause when you use a ROLLUP operator and only one record satisfies the query predicates.



RESOLUTION
To resolve this problem, obtain the latest service pack for Microsoft SQL Server 2000. For additional information, click the following article number to view the article in the Microsoft Knowledge Base:

290211 INF: How to Obtain the Latest SQL Server 2000 Service Pack



STATUS
Microsoft has confirmed that this is a problem in Microsoft SQL Server 2000. This problem was first corrected in Microsoft SQL Server 2000 Service Pack 2.



MORE INFORMATION
You can use this code to reproduce the problem: USE pubs GO

CREATE TABLE t ( x varchar(5) )

INSERT INTO t VALUES ( 'A' ) INSERT INTO t VALUES ( 'B' ) GO

SELECT GROUPING(x) AS g0,x FROM t WHERE (x = 'A') GROUP BY x WITH ROLLUP ORDER BY GROUPING(x) DESC GO

--This query returns the results in ascending order instead of descending order.

The result of the query is: g0  x      - 0   A 1    NULL

(2 row(s) affected) The query produces the correct result if multiple rows return. For example: SELECT GROUPING(x) AS g0, x FROM t WHERE (x = 'A') OR (x = 'B') GROUP BY x WITH ROLLUP ORDER BY GROUPING(x) DESC The query result is: g0  x      - 1   NULL 0   A 0    B

(3 row(s) affected)
