SQL SERVER – Unable to Attach Database – File Activation Failure – The Log Cannot be Rebuilt
An exception occurred while executing a Transact-SQL statement or batch. (Microsoft.SqlServer.ConnectionInfo)
Could not open new database 'MyLostDB'. CREATE DATABASE is aborted.
File activation failure. The physical file name "C:\xxx\MyLostDB.ldf" may be incorrect.
The log cannot be rebuilt because there were open transactions/users when the database was shutdown, no checkpoint occurred to the database, or the database was read-only. This error could occur if the transaction log file was manually deleted or lost due to a hardware or environment failure. (Microsoft SQL Server, Error: 1813)
An undocumented option called as ATTACH_FORCE_REBUILD_LOG
CREATE DATABASE <YOURDBNAME>
ON (FILENAME = 'D:\<YOURMDFNAME>.mdf')
