attach a MDF without LDF
Create a new database with the same name and same MDF and LDF files
Stop sql server and rename the existing MDF to a new one and copy the original MDF
to this location and delete the LDF files
Start SQL Server
Now your database will be marked suspect
Update the sysdatabases to update to Emergency mode. This will not use LOG files in start up
Sp_configure "allow updates", 1
go
Reconfigure with override
GO
Update sysdatabases set status = 32768 where name = "BadDbName"
go
Sp_configure "allow updates", 0
go
Reconfigure with override
GO
Restart sql server. now the database will be in emergency mode
Now execute the undocumented DBCC to create a log file
DBCC REBUILD_LOG(dbname,'c:\dbname.ldf') -- Undocumented step to create a new log file
(replace the dbname and log file name based on ur requirement)
Execute sp_resetstatus
Restart SQL server and see the database is online
