If your project’s database is in suspect mode, then no transaction will take place until and unless you repair your database. That causes a show stopper for your up and running application. Here, you will find a way to get out of this.
Your Database is in Suspect Mode. I guess, you haven’t experienced this problem till now. But, if it comes to you and if the database is LIVE, then it’s time to read this article to get out of this tension.
Using the Code
If you find your database in Suspect mode, then please keep your nerve strong. Just proceed step by step what I am written below. I think you will get out of this trouble. SQL Server 2005 introduced a new DB Status called Emergency. This mode can change the DB from Suspect mode to Emergency mode, so that you can retrieve the data in read only mode. The steps are… After executing the script given below, you will get back your database in operational mode. Actually I have tried with two of my existing live systems and found no data loss.
Note: Obviously there are two more options available. Run
REPAIR_ALLOW_DATA_LOSS to ensure the database is returned to a structurally and transitionally consistent state. Here are a few things to bear in mind about emergency mode repair: it’s a one-way operation. Anything it does cannot be rolled back or undone. If this worries you (if someone ever got into that state, then surely don’t have the healthy concern about data that they should have in the first place) then make a copy of the damaged database before you run emergency mode repair.
As it’s a one-way operation, you cannot wrap it in an explicit user-transaction.
It’s the only repair option available in emergency mode – if you try to use
REPAIR_REBUILD, then it won’t work.
- EXEC sp_resetstatus ‘yourDBname’;
- ALTER DATABASE yourDBname SET EMERGENCY /*for 2005*/
- DBCC checkdb(‘yourDBname’)
- ALTER DATABASE yourDBname SET SINGLE_USER WITH ROLLBACK IMMEDIATE
- DBCC CheckDB (‘yourDBname’, REPAIR_ALLOW_DATA_LOSS)
- DBCC CHECKTABLE (‘tableName’, REPAIR_ALLOW_DATA_LOSS)
- ALTER DATABASE yourDBname SET MULTI_USER
