Row Counts for every user table in a database?

Hello again, everyone!
I'm attempting to make a stored procedure that gets the rowcount for every
table in a given database. To do this, obviously, I need to use a cursor.
The problem I'm having is with passing the database name to the procedure,
and having it evaluate and run the expression. Here is my code thus far:
----
--
create procedure z_sp_CountTest
@.DatabaseName nvarchar(100)
as
-- Declare the Variables
Declare
@.SQL nvarchar(300),
@.DatabaseSysObjects nvarchar(100),
@.TableName sysname
-- Make a string for the database name and table to get all table names from
Set @.DatabaseSysObjects = @.DatabaseName + '.dbo.sysobjects'
-- Create a SQL string to get the user table names
Set @.SQL = 'Select name from ' + @.DatabaseSysObjects + ' where xtype = ''U''
order by name'
-- Declare the cursor to get the Table Names
Declare GetTableRowCounts Cursor
Local
For
exec master.dbo.sp_executesql @.SQL
Open GetTableRowCounts
Fetch next from GetTableRowCounts into @.TableName
While (@.@.FETCH_STATUS = 0)
Begin
[Do what I want with the rowcounts here.. Will require a statement similiar
to the above]
End
CLOSE GetTableRowCounts
DEALLOCATE GetTableRowCounts
----
--
However, whenever I do a syntax check, I always get:
Server: Msg 156, Level 15, State 1, Procedure z_sp_CountTest, Line 21
Incorrect syntax near the keyword 'exec'.
Can anyone give me a clue as to what it could possibly be?
I've tried almost every itteration of the exec line I could think of. This
includes leaving the master.dbo out, trying just exec, and many other
hair-brainned ideas.
Any help would be great!You'll probably have to dump the results from the @.SQL into a temp table and
run the cursor on the temp table.

You can use a non-documented sp sp_msforeachtable (not recommended in
production code) or create a cursor to traverse information_schema.tables.
You can also pull that info from the system table sysindexes, but be sure to
first execute "dbcc updateusage (...) with count_rows".
use northwind
go
exec sp_msforeachtable 'select ''?'', count(*) from ?'
go
create table #t (
tname sysname,
rcnt int
)
declare @.tn sysname
declare @.sql nvarchar(4000)
declare my_cursor cursor local fast_forward
for
select
quotename(table_schema) + '.' + quotename(table_name)
from
information_schema.tables
where
objectproperty(object_id(quotename(table
_schema) + '.' +
quotename(table_name)), 'IsUserTable') = 1
and objectproperty(object_id(quotename(table
_schema) + '.' +
quotename(table_name)), 'IsMSShipped') = 0
open my_cursor
while 1 = 1
begin
fetch next from my_cursor into @.tn
if @.@.error != 0 or @.@.fetch_status != 0 break
set @.sql = N'select ''' + @.tn + N''', count(*) from ' + @.tn
insert into #t
exec sp_executesql @.sql
end
close my_cursor
deallocate my_cursor
select * from #t order by 1
drop table #t
go
dbcc updateusage (0) with count_rows
go
select object_name([id]) as table_name, rowcnt
from sysindexes
where indid in (0, 1) and objectproperty([id], 'IsUserTable') = 1
order by 1
go

When declaring a cursor, a select statement should go after "For". The
"exec" command is not allow here.

There are plenty such operations and situations, but it has been improved wi

I suppose that I'm really lucky to be working soley with SQL2005 now :-)
