SQL Server 2000: how do i get a list of tables and the row counts?

Question

I know that I can get a list of tables with

SELECT TABLE_NAME FROM information_schema.tables 
WHERE NOT TABLE_NAME='sysdiagrams' 
  AND TABLE_SCHEMA = 'dbo' 
  AND TABLE_TYPE= 'BASE TABLE'

But I'm not sure how to modify that to get a 2nd column with the current count of rows for the tables. I though of something like this:

DECLARE @tbl VARCHAR(200)
(SELECT @tbl = TABLE_NAME, TABLE_NAME,
(SELECT COUNT(ID) AS Cnt FROM @tbl)
FROM information_schema.tables 
WHERE NOT TABLE_NAME='sysdiagrams' 
  AND TABLE_SCHEMA = 'dbo' 
  AND TABLE_TYPE= 'BASE TABLE')

I know the above is not valid T-SQL but I think it gets the point of what I would like the have done. This is for SQL Server 2000. I would prefer not to use store procedures if at all possible.

A quick and dirty way (includes uncommitted changes and possibly forwarding pointers on heaps)

select o.name, rows 
from sysindexes i join sysobjects o on o.id=i.id
where indid < 2 and type='U'

exec sp_MSforeachtable 'select count(*) as nr_of_rows, ''?'' as table_name from ?'

this produces a separate query for each table, not a single query with all the information. – Justin808 Mar 03 '11 at 22:30
@Justin808: yes, but it will return accurate row counts – Mar 03 '11 at 22:32
True, in my situation the approximate count all in 1 table works is acceptable and less work (for me). it is good to know how to get the accurate counts though. – Justin808 Mar 03 '11 at 22:35

You can go whole hog on this one. The problem with using sysIndexes to get rowcounts is that they're not always up to date. There is a way to make them all up to date, though. The following code will give you row counts for each table and a whole bunch more.

/**********************************************************************************************************************
 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 function.
 2. Must comment out 1 "Schema" in the SELECT list below prior to use.  See the adjacent comments for more info.
