How to repair a SQL Server 2005 Suspect database
Posted by Manoj Garg on July 17, 2008
Sometimes when you connect to your database server, you may find it in suspect mode. Your database server won’t allow you to perform any operation on that database until the database is repaired.
A database can go in suspect mode for many reasons like improper shutdown of the database server, corruption of the database files etc.
To get the exact reason of a database going into suspect mode can be found using the following query,
DBCC CHECKDB (‘YourDBname’) WITH NO_INFOMSGS, ALL_ERRORMSGS
Output of the above query will give the errors in the database.
To repair the database, run the following queries in Query Analyzer,
EXEC sp_resetstatus ‘yourDBname';
ALTER DATABASE yourDBname SET EMERGENCY
ALTER DATABASE yourDBname SET SINGLE_USER WITH ROLLBACK IMMEDIATE
DBCC CheckDB (‘yourDBname’, REPAIR_ALLOW_DATA_LOSS)
ALTER DATABASE yourDBname SET MULTI_USER
and you are done. :)
You should keep one thing in mind while using the above queries that the repair mode used here , REPAIR_ALLOW_DATA_LOSS, is a one way operation i.e. once the database is repaired all the actions performed by these queries can’t be undone. There is no way to go back to the previous state of the database. So as a precautionary step you should take backup of your database before executing above mentioned queries.
