  Hi All,

  I have a table with about 1.8 bln records. However, when I run

  sp_spaceused or

  declare

  @table_name varchar(255)

  set

  @table_name = 'myTable''

  select

  rows from sysindexes

  where

  id = OBJECT_ID(@table_name) and

  indid

  < 2

  number of rows in both cases is same and it is INCORRECT.

  I managed to get the correct number of rows, however even with update usage of the database:

  1.

  DBCC updateusage ('myDatabase')

  2

  .sp_spaceused 'myTable', @updateusage = true

  sp_spaceused is showing wrong number (month old or so) despite multiple (mlns) inserts\updates\deletes.

  Anybody know how to get sp_spaceused to work on very big tables.

  TIA

  I always use  DBCC updateusage ('myDatabase')   with count_rows

  and I run sp_updatestats afterward.
