  • Whether the hotfix package is replaced by any other 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.
