Bug #: 50001299 (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
When you run a query that references a temporary table in SQL Server 2005, the query may fail, and you may receive the following error message:

Internal error. Buffer provided to read column value is too small. Run DBCC CHECKDB to check for any corruption.

However, if you run the DBCC CHECKDB statement to check for database corruption, the DBCC CHECKDB statement does not report any errors.



CAUSE
This problem occurs because temporary tables are cached in SQL Server 2005. The cached temporary tables are reused if the table schema remains the same. However, a cached temporary table may be incorrectly reused even if the table schema has changed.



RESOLUTION
The fix for this issue was first released in Cumulative Update 2. 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:

936305 Cumulative update package 2 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.

937137 The SQL Server 2005 builds that were released after SQL Server 2005 Service Pack 2 was released

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.
