Bug #: 50001365 (SQL Hotfix)



Microsoft distributes Microsoft SQL Server 2005 fixes as one downloadable file. Because the fixes are cumulative, each new release contains all the hotfixes and all the security fixes that were included with the previous SQL Server 2005 fix release.



SYMPTOMS
In Microsoft SQL Server 2005 Service Pack 2, you run a query that selects many columns and that joins many tables. When you do this, you may receive the following error messages:

Error message 1

8624 error is being generated and a mini-dump written by the exception handler.

Error message 2

Msg 8624, Level 16, State 1, Line 1

Internal Query Processor Error: The query processor could not produce a query plan. For more information, contact Customer Support Services.

Additionally, a minidump file is generated in the SQL Server log.



CAUSE
This issue occurs because the query runs under the execution context of the sp_cursoropen stored procedure. The SQL Server 2005 Database Engine generates an exception when SQL Server 2005 tries to create an execution plan.



RESOLUTION
The fix for this issue was first released in Cumulative Update 3. For more information about how to obtain this cumulative update package for SQL Server 2005 Service Pack 2, click the following article number to view the article in the Microsoft Knowledge Base:

939537 Cumulative update package 3 for SQL Server 2005 Service Pack 2

Note Because the builds are cumulative, each new fix release contains all the hotfixes and all the security fixes that were included with the previous SQL Server 2005 fix release. Microsoft recommends that you consider applying the most recent fix release that contains this hotfix.

Microsoft SQL Server 2005 hotfixes are created for specific SQL Server service packs. You must apply a SQL Server 2005 Service Pack 2 hotfix to an installation of SQL Server 2005 Service Pack 2. By default, any hotfix that is provided in a SQL Server service pack is included in the next SQL Server service pack.



STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the &quot;Applies to&quot; section.
