SQL SERVER: ROW_NUMBER () vs. DENSE_RANK ()

ROW_NUMBER() will be used to achieve first two goals as ROW_NUMBER() return sequential row number within a partition of result set. And for last column we will use DENSE_RANK(), which will return rank of rows within the partition of a result set.

--Create temporary table for query testing
CREATE TABLE #TeamPlayer
   (
     Team VARCHAR(25),
     PlayerName VARCHAR(25)
   )
GO

-- Insert temporary records
INSERT  INTO #TeamPlayer ( Team, PlayerName )
       SELECT  'South Zone',
               'SZ_Player1'
       UNION ALL
       SELECT  'South Zone',
               'SZ_Player2'
       UNION ALL
       SELECT  'South Zone',
               'SZ_Player3'
       UNION ALL
