How to fetch the row count for all tables in a SQL SERVER database [duplicate]

Solution 1:

The following SQL will get you the row count of all tables in a database:

CREATE TABLE #counts
(
    table_name varchar(255),
    row_count int
)

EXEC sp_MSForEachTable @command1='INSERT #counts (table_name, row_count) SELECT ''?'', COUNT(*) FROM ?'
SELECT table_name, row_count FROM #counts ORDER BY table_name, row_count DESC
DROP TABLE #counts

The output will be a list of tables and their row counts.

If you just want the total row count across the whole database, appending:

SELECT SUM(row_count) AS total_row_count FROM #counts

will get you a single value for the total number of rows in the whole database.

Solution 2:

If you want to by pass the time and resources it takes to count(*) your 3million row tables. Try this per SQL SERVER Central by Kendal Van Dyke.

Row Counts Using sysindexes If you're using SQL 2000 you'll need to use sysindexes like so:

-- Shows all user tables and row counts for the current database 
-- Remove OBJECTPROPERTY function call to include system objects 
SELECT o.NAME,
  i.rowcnt 
FROM sysindexes AS i
  INNER JOIN sysobjects AS o ON i.id = o.id 
WHERE i.indid < 2  AND OBJECTPROPERTY(o.id, 'IsMSShipped') = 0
ORDER BY o.NAME

If you're using SQL 2005 or 2008 querying sysindexes will still work but Microsoft advises that sysindexes may be removed in a future version of SQL Server so as a good practice you should use the DMVs instead, like so:

-- Shows all user tables and row counts for the current database 
-- Remove is_ms_shipped = 0 check to include system objects 
-- i.index_id < 2 indicates clustered index (1) or hash table (0) 
SELECT o.name,
  ddps.row_count 
FROM sys.indexes AS i
  INNER JOIN sys.objects AS o ON i.OBJECT_ID = o.OBJECT_ID
  INNER JOIN sys.dm_db_partition_stats AS ddps ON i.OBJECT_ID = ddps.OBJECT_ID
  AND i.index_id = ddps.index_id 
WHERE i.index_id < 2  AND o.is_ms_shipped = 0 ORDER BY o.NAME

Solution 3:

Works on Azure, doesn't require stored procs.

SELECT t.name, s.row_count from sys.tables t
JOIN sys.dm_db_partition_stats s
ON t.object_id = s.object_id
AND t.type_desc = 'USER_TABLE'
AND t.name not like '%dss%'
AND s.index_id IN (0,1)

Credit.

Solution 4:

This one looks better than the others I think.

USE  [enter your db name here]
GO

SELECT      SCHEMA_NAME(A.schema_id) + '.' +
        --A.Name, SUM(B.rows) AS 'RowCount'  Use AVG instead of SUM
          A.Name, AVG(B.rows) AS 'RowCount'
FROM        sys.objects A
INNER JOIN sys.partitions B ON A.object_id = B.object_id
WHERE       A.type = 'U'
GROUP BY    A.schema_id, A.Name
GO

Solution 5:

Short and sweet

sp_MSForEachTable 'DECLARE @t AS VARCHAR(MAX); 
SELECT @t = CAST(COUNT(1) as VARCHAR(MAX)) 
+ CHAR(9) + CHAR(9) + ''?'' FROM ? ; PRINT @t'

Output:
