MSSQL 2000: How to get space used, row count and other table specific informations

/**********************************************************************************************************************
Purpose:
Returns a single result set similar to sp_Space used for all user tables at once.

Notes:
1. May be used as a view, stored procedure, or table-valued funtion.
2. Must comment out 1 “Schema” in the SELECT list below prior to use. See the adjacent comments for more info.

Revision History:
Rev 00 – 22 Jan 2007 – Jeff Moden
– Initital creation for SQL Server 2000
Rev 01 – 11 Mar 2007 – Jeff Moden
– Add automatic page size determination for future compliance
Rev 02 – 05 Jan 2008 – Jeff Moden
– Change “Owner” to “Schema” in output. Add optional code per Note 2 to find correct schema name

–===== Ensure that all row counts, etc is up to snuff
— Obviously, this will not work in a view or UDF and should be removed if in a view or UDF. External code should
— execute the command below prior to retrieving from the view or UDF.
