I need to send a SQL query to a database that tells me how many rows there are in a table. I could get all the rows in the table with a SELECT and then count them, but I don't like to do it this way. Is there some other way to ask the number of the rows in a table to the SQL server?
This question is related to

Yes, SELECT COUNT(*) FROM TableName
select sum([rows])
from sys.partitions
where object_id=object_id('tablename')
and index_id in (0,1)
is very fast but very rarely inaccurate.
Why don't you just right click on the table and then properties -> Storage and it would tell you the row count. You can use the below for row count in a view
SELECT SUM (row_count)
FROM sys.dm_db_partition_stats
WHERE object_id=OBJECT_ID('Transactions')
AND (index_id=0 or index_id=1)`
Use This Query :
Select
S.name + '.' + T.name As TableName ,
SUM( P.rows ) As RowCont
From sys.tables As T
Inner Join sys.partitions As P On ( P.OBJECT_ID = T.OBJECT_ID )
Inner Join sys.schemas As S On ( T.schema_id = S.schema_id )
Where
( T.is_ms_shipped = 0 )
AND
( P.index_id IN (1,0) )
And
( T.type = 'U' )
Group By S.name , T.name
Order By SUM( P.rows ) Desc
Here is the Query
select count(*) from tablename
or
select count(rownum) from studennt
The index statistics likely need to be current, but this will return the number of rows for all tables that are not MS_SHIPPED.
select o.name, i.rowcnt
from sys.objects o join sys.sysindexes i
on o.object_id = i.id
where o.is_ms_shipped = 0
and i.rowcnt > 0
order by o.name
