be used to repair the index for a given system table. System table indexes are crucial elements of a smooth-running SQL Server, making it necessary for you to be able to easily fix corrupted indexes.
You know you have a corrupt system table index when you get log error 605. Fixing the index with sp_fixindex can save you the hassle of having to restore the database from a backup.
Stored procedure syntax
dbname is the name of the database to repair, tablename is the name of the system table with the damaged index and index_id is the index ID number for the problem index. If you don't know the index ID number, you can derive it with a quick query:
SELECT NAME, INDID FROM SYSINDEXES WHERE
Putting the database in single-user mode
You must first put the database in single-user mode before you can run sp_fixindex. One way to do this is with the sp_dboption procedure:
EXEC SP_DPOPTION <database>, SINGLE, TRUE
Taking the database out of single-user mode
To take the database out of single-user mode, use the following procedure:
EXEC SP_DPOPTION <database>, SINGLE, FALSE
You must also run sp_fixindex separately for each index you want to repair. It is possible to run sp_fixindex against the system catalogs, but you must stop and restart the SQL Server service after you do this.
Always run DBCC CHECKDB and CHECKALLOC statements against the repaired database after running sp_fixindex.
