MSSQL 2012 logs DB corrupted

[amaurylaurent]

I have a server that crashed and i'm trying to move MSSQL database files onto another server. They have all reattached except for one. I'm getting the following error:

Microsoft SQL-DMO (ODBC SQLState: HY000)
Error 9004: An error occurred while processing the log for database....

I have NO backups & obviously need to mount this.

Any ideas?

Solution for this problem is quick and it is the following (Execute SQL in Given Order):

1. Connect to your database server using Microsoft SQL Server Management Studio

NOTE: replace [DatabaseName] with your database name
1. -- This query will rollback any transaction which is running on that database
2. -- and bring SQL Server database in a "single user" mode
3. ALTER DATABASE MicrosoftDynamicsAX SET SINGLE_USER WITH ROLLBACK IMMEDIATE
4.
5. -- Marking database READ_ONLY, disable logging,
6. -- and limiting access only to members of the sysadmin fixed server role
7. ALTER DATABASE MicrosoftDynamicsAX SET EMERGENCY
8.
9. -- Checks the logical and physical integrity of all the objects in the specified database
10. DBCC checkdb(MicrosoftDynamicsAX)
11.
12. -- In case of simple failure then we can use allow data loss option to recover Database
13.
14. -- DBCC CheckDB (MicrosoftDynamicsAX, REPAIR_ALLOW_DATA_LOSS)
