BUG #: 356639 (SHILOH_BUGS)



SYMPTOMS
If you use a SET ROWCOUNT statement to limit the results returned from a query, and the INSERT INTO statement contains a SELECT statement with an ORDER BY clause, the query may return incorrect data.

For example, a query may look similar to:

SET ROWCOUNT 5

INSERT INTO tbl2_name(myid) SELECT myid FROM tbl1_name ORDER BY myid

SET ROWCOUNT 0 The results returned from such a SELECT statement may be incorrect.



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

NOTE: The following hotfix was created before the release of Microsoft SQL Server 2000 Service Pack 3.

The English version of this fix must have the following file attributes or later:   Date         Version      Size         File name ---

1/31/2002   8.00.0576    7,269 KB     Sqlservr.exe NOTE: Because of file dependencies, the most recent hotfix or feature that contains the files may also contain additional files.



WORKAROUND
One of the ways to limit the rows returned in a result set is to use the TOP keyword in the SELECT statement. If you modify the query to use the TOP keyword instead of ROWCOUNT, the query works correctly.

For example, you can modify the sample query like this: INSERT INTO tbl2_name(myid) SELECT TOP 5 myid FROM tbl1_name ORDER BY myid



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 3.
