HI,
How can i get the row count of all the tables in a db
Here is the example
i got a DB with three tables A,B,C
Table A contains 20 rows
Table B contains 30 rows
Table C contains 25 rows
Now can i write a query which gets the result like
Table---rowcount
A ------20
B ------30
C ------25
i got the list of tables using select * from sys.tables
But i got stuck from here..
Thank You...

You'd either need to use dynamic SQL, or a CLR function. Dynamic SQL will be easier and won't require opening up security rules in the database.

Would look something like this:

create table #T (

TName sysname,

Rows int);

declare Tbls cursor local fast_forward for

select name

from sys.tables;

open Tbls;

declare @Tbl sysname, @Cmd nvarchar(1000);

fetch next from Tbls into @Tbl;

while @@fetch_status = 0

begin

select @Cmd = 'select ''' + @Tbl + ''', count(*) from ' + @Tbl;

insert into #T (TName, Rows)

exec(@Cmd);

fetch next from Tbls into @Tbl;

end;

select * from #T;

SELECT st.name, sip.rows

FROM sys.system_internals_partitions sip

JOIN sys.tables st ON st.object_id = sip.object_id

ORDER BY st.name

you can get counts with this:

SELECT QUOTENAME(SCHEMA_NAME(t.schema_id), ']') + '.' + QUOTENAME(t.name, ']') AS fulltable_name

, SCHEMA_NAME(t.schema_id) AS schema_name

, t.name AS table_name

, i.rows

FROM sys.tables AS t

INNER JOIN sys.sysindexes AS i

ON t.object_id = i.id

AND i.indid < 2

EDIT: Wayne's solution is better, it is using the latest tables.
