Bug #: 474105 (SQL Server 8.0)



''Microsoft distributes 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 this hotfix package
 * The prerequisites for installing the hotfix package
 * Whether you must restart your computer after you apply the hotfix package
 * Whether the hotfix package is replaced by any other hotfix package
 * Whether you must make any registry changes

SYMPTOMS
When you use a SELECT statement to fetch information from a view, and the SELECT statement returns an error message in Microsoft SQL Server 2000, the error message may contain user data. The user data is not returned in the final result if the SELECT statement successfully fetches data from a view. For example, user data is returned in an error message that is similar to the following:

Server: Msg 506, Level 16, State 1, Line 1 Invalid escape character ' ' was specified in a LIKE predicate.

STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the &quot;Applies to&quot; section.



Trace flag 3625 is required
After you apply this hotfix, you must make sure that trace flag 3625 is turned on. Additionally, you cannot dynamically turn on or turn off this trace flag by using the DBCC TRACEON statement or the DBCC TRACEOFF statement. You must configure this trace flag as a startup parameter. To do this, follow these steps:
 * 1) Start SQL Server Enterprise Manager.
 * 2) Right-click the instance of SQL Server, and then click Properties.
 * 3) Click the General tab, and then click Startup Parameters.
 * 4) In the Startup Parameters dialog box, type –T3625 in the Parameter box, click Add, and then click OK.
 * 5) In the SQL Server Properties dialog box, click OK.
 * 6) Restart the SQL Server service.

Errors that have been fixed
The following errors have been fixed in this hotfix package:
 * 151
 * 220
 * 232
 * 238
 * 244
 * 245
 * 248
 * 281
 * 506

Behavior differences between members of the sysadmin users group and non-members
If a logon user is not a member of the sysadmin users group, the error messages for the errors in the &quot;Errors that have been fixed&quot; section will mask user data as *******. The following example shows the old behavior and the new behavior.

The client receives an error message when the following query fails. SELECT cast ('abc' as int) When the query fails, the client may receive one of the following error messages:  Message 1

Server: Msg 245, Level 16, State 1, Line 1 Syntax error converting the varchar value 'abc' to a column of data type int.

</li> Message 2

Server: Msg 245, Level 16, State 1, Line 1 Syntax error converting the varchar value '******' to a column of data type int.

</li></ul>

After you apply this hotfix, message 1 is returned if a logon user is a member of the sysadmin users group. Message 2 is returned if a logon user is not a member of the sysadmin users group.

How to obtain the unmasked data values from the errors that have been fixed
If you see the errors that appear in the &quot;Errors that have been fixed&quot; section, you may want to use the data values that have been masked when you troubleshoot the errors. If you are not a member of the sysadmin users group, you will have to contact a member of the sysadmin users group for help with the following workarounds:
 * If the query is not user context-sensitive, a member of the sysadmin users group can run the query to obtain the unmasked data value for you.
 * If the query is user context-sensitive, a member of the sysadmin users group will have to turn off the trace flag 3625. Then you can run the query again to obtain the unmasked data value yourself. This workaround requires restarting SQL Server.

Note Turning off the trace flag will cause SQL Server to again experience the problem that is mentioned in the &quot;Symptoms&quot; section. Therefore, we recommend that a member of the sysadmin users group turn on the trace flag as soon as possible after you have obtained the unmasked data value.

Informational message
When trace flag 3625 is turned on, SQL Server logs the following message in the error log to indicate that some errors have been masked: SQL Server is started with trace flag 3625, this may cause user to see some error messages masked using '******'
