SQL Server 2000: how do i get a list of tables and the row counts? [duplicate]
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 ?'
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.

how about "dtproperties" and "sysdiagrams" ? these tables will show up as user table incorrectly
