Repairing a nonclustered index

Running sp_fixindex to repair a nonclustered index on sysobjects requires several additional steps.

StepsRepairing a nonclustered index on sysobjects

  1. Perform steps 1-3, as described in “Repairing the system table index with sp_fixindex,” above.

  2. Issue the following Transact-SQL query:

    1> use database_name
    2> go1> checkpoint
    2> go1> select sysstat from sysobjects
    2> where id = 1
    3> go
    

    You can use the checkpoint to identify the one or more databasess or use an all clause.

    checkpoint [all | [dbname[, dbname[, dbname.....]]]
    
  3. Save the original sysstat value.

  4. Change the sysstat column to the value required by sp_fixindex:

    1> update sysobjects
    2> set sysstat = sysstat | 4096
    3> where id = 1
    4> go
    
  5. Run sp_fixindex:

    1> sp_fixindex database_name, sysobjects, 2
    2> go
    
  6. Restore the original sysstat value:

    1> update sysobjects
    2> set sysstat = sysstat_ORIGINAL
    3> where id = object_ID
    4> go
    
  7. Run dbcc checktable to verify that the corrupted index is now fixed.

  8. Disallow updates to system tables:

    1> sp_configure "allow updates", 0
    2> go
    
  9. Turn off single-user mode:

    1> sp_dboption database_name, "single user", false
    2> go1> use database_name
    2> go1> checkpoint
    2> go
    

    You can use the checkpoint to identify the one or more databasess or use an all clause.

    checkpoint [all | [dbname[, dbname[, dbname.....]]]
