APPLIES TO

  • Microsoft SQL Server 2005 Developer Edition
  • Microsoft SQL Server 2005 Enterprise Edition
  • Microsoft SQL Server 2005 Standard Edition
  • Microsoft SQL Server 2005 Standard X64 Edition
  • Microsoft SQL Server 2005 Standard Edition for Itanium-based Systems

Bug #: 50001440 (SQL Hotfix)

Notice

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.

SUMMARY

This article describes the following about this hotfix release:

  • The issues that are fixed by the hotfix package
  • The prerequisites for installing the hotfix package
  • Whether you must restart the computer after you install the hotfix package
  • Whether the hotfix package is replaced by any other hotfix package
  • Whether you must make any registry changes
  • The files that are contained in the hotfix package


SYMPTOMS

You have a complex query in Microsoft SQL Server 2005. The execution plan of the query contains semi join operators. When you run the query, the query performance of the query is slow compared to Microsoft SQL Server 2000.

Note Typically, semi join operators are generated when the query contains the IN keyword or the EXISTS keyword.

CAUSE

This problem occurs because the query optimizer generates many more execution plans than SQL Server 2000 does. Therefore, the query optimizer may time out. When this occurs, the query optimizer stops searching for executing plans before the query optimizer fully searches all possible executing plans.

To determine whether the query optimizer times out, search for the StatementOptmEarlyAbortReason="TimeOut" expression in the XML output of the Showplan execution plan.

RESOLUTION

WORKAROUND

To work around this problem, avoid using the IN keyword or the EXISTS keyword.

STATUS

Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.

MORE INFORMATION

After you apply this hotfix, you must enable trace flag 4102 and trace flag 4118 so that the behavior reverts to the behavior in SQL Server 2000. However, we recommend that you use the method that is described in the "Workaround" section before you apply this hotfix.

You must use these trace flags for a connection on the server or for all connections on the server. If you set the trace flags at startup, the trace flags affect all connections on the server.

For more information about how to set trace flags, see the following topics in SQL Server 2005 Books Online:

  • DBCC TRACEON (Transact-SQL)
  • Trace flags (Transact-SQL)
  • DBCC TRACESTATUS (Transact-SQL)
  • Breaking changes to Database Engine features in SQL Server 2005
