Bug #: 50000230 (SQL Hotfix)



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.



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
Consider the following scenario. In Microsoft SQL Server 2000, you run a query that uses the ORDER BY clause to sort a column in a table. The table has an index. In this scenario, the result may be sorted in the wrong order.

This problem occurs if one of the following conditions is true:   The query uses the IN keyword. For example, the query uses the following predicate. a IN (2, 10, 12, 23)   The query uses a predicate that is equivalent to a predicate that uses the IN keyword. For example, the query uses the following predicate. (a = 2 or a = 10 or a = 12 or a = 23) 

The following examples are examples of this problem:
 * In the index definition, a column is sorted in ascending order. You run a query that uses the ORDER BY clause to sort the column in descending order. When you run the query, the result is sorted in ascending order.
 * In the index definition, a column is sorted in descending order. You run a query that uses the ORDER BY clause to sort the column in ascending order. When you run the query, the result is sorted in descending order.



RESOLUTION
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.
