KB958611 - FIX: You may receive incorrect results when you run a query that references three or more tables in the FROM clause in SQL Server 2008

Bug #: 50003634 (SQL Hotfix)
Bug #: 50003611 (SQL Hotfix)

Microsoft distributes Microsoft SQL Server 2008 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 2008 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

In Microsoft SQL Server 2008, you create a filtered index on a table. Then, you run a query that references three or more tables in the FROM clause. When you run the query, you may receive incorrect results.

Cause

This problem occurs because the optimizer uses the filtered index even though the search condition that is defined in the filtered index is not specified in the query.
