Using A Cursor_
DECLARE @table VARCHAR(255),
@cmd VARCHAR(500)

CREATE TABLE #tableData (TableName VARCHAR(255), TotalRows INT)

DECLARE cursor_tableData CURSOR FOR
SELECT table_name FROM Information_Schema.Tables
WHERE table_type = 'base table'

OPEN cursor_tableData

FETCH NEXT FROM cursor_tableData INTO @table
WHILE @@fetch_status = 0
BEGIN
SET @cmd = 'SELECT ''' + @table + ''', COUNT(*) FROM ' + @table
INSERT INTO #tableData EXEC (@cmd)
FETCH NEXT FROM cursor_tableData INTO @table
END
CLOSE cursor_tableData
DEALLOCATE cursor_tableData

SELECT * FROM #tableData ORDER BY TotalRows DESC
DROP TABLE #tableData



The following methods are using un-documented stored procedure 'sp_msFOREachTable'. There is a cursor declared in that which loops through each table in the current database and executes a script that you define.
