The joy of sp_spaceused

,

Copy and paste the code below into AdventureWorks2008 and execute against the DB you want table metrics for. The limitation of this script is that it can only give table metrics for the current DB as sp_spaceused only works for the current DB. Perhaps the next target will be to modify this so as to get the tables for all databases within a server.

/*
script to get table sizes and row count within a database using sp_spaceused.
*/-- lets create a table holder for our results.
DECLARE  @t_sizes_BS TABLE (
[Name]   VARCHAR(60)
