Is it possible to get the last value updated in a table after an update operation has been conducted

WHERE DATEDIFF( dd, GETDATE(), @myDate )
BETWEEN DATEDIFF( dd, GETDATE(), @dateFrom )
AND     DATEDIFF( dd, GETDATE(), @dateTo )

You can use sp_attach_db, sp_attach_single_file_db

Remarks<br />
sp_attach_db should only be executed on databases that were previously detached from the database server using an explicit sp_detach_db operation.

Attempt 1 (Strike 1): TRIED TO EXECUTE IN QUERY ANALYZER<br />
EXEC sp_attach_db @dbname = 'NewDatabase', <br />
 @filename1 = 'c:\mssql7\data\ArchiveData.mdf', <br />
 @filename2 = 'c:\mssql7\data\ArchiveLog.ldf'<br />
 <br />
SERVER MESSAGES:<br />
Server: Msg 9004, Level 21, State 3, Line 1<br />
The log for database 'NewDatabase' is corrupt.<br />
Connection Broken<br />
 <br />
(Continued) ISSUE:<br />
The log file is corrupt, so I tried to attach the mdf file to a new database using the single file attach method.<br />
 <br />
Attempt 2 (Strike 2):TRIED TO EXECUTE IN QUERY ANALYZER<br />
EXEC sp_attach_single_file_db @dbname = 'NewDatabase', <br />
 @physname = 'c:\mssql7\data\ArchiveData.mdf'<br />
 <br />
SERVER MESSAGES:<br />
Server: Msg 945, Level 14, State 2, Line 1<br />
Database 'NewDatabase' cannot be opened because some of the files could not be activated.<br />
Server: Msg 1813, Level 16, State 2, Line 1<br />
Could not open new database 'NewDatabase'. CREATE DATABASE is aborted.<br />
 <br />
Attempt 3 (Strike 3 --- Struck OUT): tried to fool SQL Server by switch mdf files. <br />
I created a brand new database called Archive.<br />
I detached the database.<br />
I renamed the Archive_Data.mdf to Archive_DataOld.mdf<br />
I applied the switch by renaming the AchiveData.mdf  to Archive_Data.mdf <br />
I left the brand new log file alone.<br />
I attempted to attach the database<br />
 <br />
EXEC sp_attach_db @dbname = 'Archive', <br />
 @filename1 = 'c:\mssql7\data\Archive_Data.mdf', <br />
 @filename2 = 'c:\mssql7\data\Archive_Log.ldf'<br />
 <br />
 <br />
also tried<br />
 <br />
EXEC sp_attach_db @dbname = 'NewDatabase', <br />
 @filename1 = 'c:\mssql7\data\Archive_Data.mdf', <br />
 @filename2 = 'c:\mssql7\data\Archive_Log.ldf'<br />
