FIX: Incorrect results when you run a query against a database that has a 90 collation in SQL Server 2008 or in SQL Server 2008 R2

Applies to: SQL Server 2008 DeveloperSQL Server 2008 EnterpriseSQL Server 2008 Express

Microsoft distributes Microsoft SQL Server 2008 SP2 or Microsoft SQL Server 2008 R2 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 SP2 or SQL Server 2008 R2 fix release.

Symptoms


Consider the following scenario:
  • In Microsoft SQL Server 2008 or in Microsoft SQL Server 2008 R2, you set a 90 collation as the collation of a database, or you use a 90 collation in a query collate option.

    For example, you set Japanese_90_CI_AS as the collation of the database. Or, you use a 90 collation that resembles the following in a query collate option:
    Select * from repro_table where c1 like '1%5' collate Japanese_90_CI_AS
  • You try to run a query that includes a LIKE operator against the database. The pattern of the LIKE operator is "%_" or "%[]."
In this scenario, the query returns incorrect results.
