Microsoft distributes Microsoft SQL Server 2000 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 2000 fix release.

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


In rare situations, Microsoft SQL Server 2000 stops responding when you cancel a query or when a query time-out occurs. Additionally, error messages that resemble the following are logged in the SQL Server error log file:

This problem occurs if the following conditions are true:
  • The query performs operations on binary large object (BLOB) data types. Examples of binary large object data types include the Text data type, the NText data type, and the Image data type.
  • The query contains the UNION operator or the OUTER JOIN operator.
  • The query spends significant time processing the binary large object data types.


The installer does not install this hotfix correctly on x64-based systems. This installation issue occurs when the following conditions are true:
  • The system uses the Advanced Micro Devices (AMD) AMD64 processor architecture or the Intel Extended Memory 64 Technology (EM64T) processor architecture.

    Note This issue does not occur on systems that use the Intel Itanium processor architecture.
  • The system is running a 64-bit version of the Microsoft Windows Server operating system.
  • The system is running a 32-bit version of SQL Server 2000.
We have corrected this installation issue in later builds of SQL Server 2000, starting with version 8.00.2244. When a customer who is running SQL Server 2000 on an x64-based system requests this hotfix, we will provide a build that includes this hotfix and that can be installed correctly on an x64-based system. The build that we provide will be version 8.00.2244 or a later version.

To work around this problem, use one of the following techniques:
  • Avoid canceling the query.
  • Avoid using time-consuming operations on the binary large object data types. These operations make the query resource intensive and may slow down the server.
  • Rewrite the query to avoid the UNION operator or the OUTER JOIN operator.


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