Bug #: 474800 (SQL Server 8.0)



''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 this hotfix package
 * The prerequisites for applying this hotfix package
 * Whether you must restart the computer after you apply this hotfix package
 * Whether this hotfix package is replaced by any other hotfix package
 * Whether you must make any registry changes after you apply this hotfix package
 * The files that are contained in this hotfix package



SYMPTOMS
In Microsoft SQL Server 2000, when you query a view that was created by using the VIEW_METADATA option, an access violation may occur.

In the Itanium architecture versions of SQL Server 2000, you may notice the following symptoms:
 * An access violation in the sqlservr!memcpy function near offset 0x180
 * The assertion &quot;cbSize <= m_cbMaxBlock&quot; in Memblk.cpp at line 166

In the 32-bit versions of SQL Server 2000, you may notice the following symptom:
 * An access violation in the sqlservr!CRowFmtTds::InitODS function near offset 0xfb

For a list of all publicly released SQL Server 2000 post-Service Pack 4 hotfixes, see the following article in the Microsoft Knowledge Base:

894905 Cumulative list of the hotfixes that are available for SQL Server 2000 Service Pack 4



CAUSE
This problem may occur when the query references the cached view memory structure after the memory structure has been flushed from the procedure cache.



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.
