Get Records counts for all tables in a Database

Suppose we want to find the number of records in each table from a data base we need to write the Query to get count of each table. It is some tedious task.
Here we will learn how to create the count script of the all tables in a database.
SELECT DB_NAME() As [Database Name],
             obj.name As [Table name],
            'Select '''+ obj.name + ''' as [Table Name], count(*) as [Number of records]  From '
                                + DB_NAME() + '.' + SCHEMA_NAME(SCHEMA_ID) + '.'+obj.name
          AS [Script generator to get records counts for all tables]
FROM    sys.objects obj
WHERE   obj.[type] = 'U'
ORDER BY obj.name


With the help of this sql script we will get the Database name, table name and the sql script to get the record counts.
  
Now the count script is ready
We need to run one by one and get the result
  
Again it is bit tedious task.
There is another way to get this very easy. Using System Stored procedures  sp_MSforeachtable.
We find these stored procedures in Master Database
  
We will read the value of the stored procedures and store it on the Temp table and finally we get the values from the Temp table.
use  AdventureWorksDW2008R2
CREATE TABLE #TempRecordsCounts
    ([Table Name] VARCHAR(200) ,
     [Number of records] INT)
EXEC sp_MSforeachtable 'insert into #TempRecordsCounts select ''?'', count(*) from ?'
SELECT  *
FROM    #TempRecordsCounts
ORDER BY [Number of records] desc

DROP TABLE #TempRecordsCounts

See the output
