FIX: Rows that include a NULL column may not be deleted when you delete rows from a table by using "<ImageColumnName> is NULL" as the condition in the WHERE clause in SQL Server 2005

Extended support for SQL Server 2005 ends on April 12, 2016

If you are still running SQL Server 2005 after April 12, 2016, you will no longer receive security updates and technical support. We recommend upgrading to SQL Server 2014 and Azure SQL Database to achieve breakthrough performance, maintain security and compliance, and optimize your data platform infrastructure. Learn more about the options for upgrading from SQL Server 2005 to a supported version here.
