BUG #: 469145 (SHILOH_BUGS)
A call to the xp_sendmail extended stored procedure might cause a handled Access Violation when all the following conditions are met:
The xp_sendmail call must use the @query parameter to send a recordset.
The query passed to the @query parameter must include a COMPUTE clause.
The query must return no rows.
Here is an example of a query that might experience this problem:
EXEC master..xp_sendmail @recipients = 'recipient_email_address', @message = 'Total Sum of Job ID' , @subject = 'Compute Sum', @width = 133 , @query = 'SELECT emp_id, fname, minit, lname, job_id, job_lvl, pub_id FROM pubs.dbo.employee WHERE 1=0 COMPUTE SUM (job_id)'
Note This problem is a regression that only affects a small number of post-SQL Server 2000 Service Pack 3 hotfix releases. This problem only applies to server computers that are running SQL Server 2000 hotfix builds between build 780 and 807 (inclusive). Check the version of the Sqlmap70.dll file that is in the BINN folder of the instance of SQL Server to determine if the instance is affected. The affected file version has the following attributes:
Date Time Version Size File name -------------------------------------------------------------- 28-Feb-2003 01:34 2000.80.778.0 176,696 bytes Sqlmap70.dll

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:

Note This hotfix (build 811) can only be applied to SQL Server 2000 Service Pack 3.
The English version of this fix has the file attributes (or later) that are listed in the following table. The dates and times for these files are listed in coordinated universal time (UTC). When you view the file information, it is converted to local time. To find the difference between UTC and local time, use the Time Zone tab in the Date and Time tool in Control Panel.
Note Because of file dependencies, the most recent hotfix or feature that contains the files may also contain additional files.
Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article. This problem was first corrected in Microsoft SQL Server 2000 Service Pack 4.
To work around the problem you can modify the query so that it only performs a COMPUTE when there are rows to be returned. For example, you can modify the query in the "Symptoms" section as follows to avoid the problem:
EXEC master..xp_sendmail @recipients = 'recipient_email_address', @message = 'Total Sum of Job ID' , @subject = 'Compute Sum', @width = 133 , @query = 'IF EXISTS (SELECT 1 FROM pubs.dbo.employee WHERE 1=0) SELECT emp_id, fname, minit, lname, job_id, job_lvl, pub_id FROM pubs.dbo.employee WHERE 1=0 COMPUTE SUM (job_id) ELSE SELECT ''No Data'' as [SUM]'
