Count Rows in all the Tables of a SQL Server Database

To get an accurate value of all the rows in a SQL Server table, use DBCC UPDATEUSAGE. DBCC UPDATEUSAGE corrects the rows, used pages, reserved pages, leaf pages and data page counts for each partition in a table or index. Here’s a query that first uses DBCC UPDATEUSAGE and then count all the rows in all the tables of a database using the undocumented stored procedure sp_msForEachTable

USE AdventureWorks
GO
DECLARE @DynSQL NVARCHAR(255) 
SET @DynSQL = 'DBCC UPDATEUSAGE (' + DB_NAME() + ')' 
EXEC(@DynSQL) 

EXEC sp_msForEachTable
'SELECT PARSENAME(''?'', 1) as TableName,
COUNT(*) as NumberOfRows FROM ?'

OUTPUT (Partial)
