be other options out there. This is something that worked for me once but there
are no guarantees that it will work at all times.
Stop SQL Server instance -> Copy MDF and LDF files to another location -> Delete original MDF and LDF files -> Start SQL Server instance again -> Create new database with exact same name and file names -> Stop SQL Server -> overwrite newly
created MDF and LDF.
your database should be back online. If it is then go ahead and put it into EMERGANCY mode and SINGLE USER mode.
ahead and execute DBCC CHECKDB like
DBCC CHECKDB (databaseName, REPAIR_ALLOW_DATA_LOSS)
If you can get to this and execute last command
successfully you should be good. If not then your only options are restoring
from backup and/or using ms sql mdf repair tool for repair your .mdf file. I
can advise one it’s MDF Repair Kit. It very helped me once. http://www.mdf.repair/
