Also, you can try this one:
DECLARE @Table TABLE
AUTOID INT PRIMARY KEY ,
RNO INT ,
NAME NVARCHAR(50)
INSERT @Table
( AUTOID, RNO, NAME )
VALUES ( 1, 1, 'ACCOUNTS' ),
( 2, 1, 'IT' ),
( 3, 1, 'SALES' ),
( 4, 2, 'MARKETING' ),
( 5, 2, 'SALES' ),
( 6, 2, 'IT' ),
( 7, 3, 'MAINTANANCE' ),
( 8, 3, 'SUPPORT' ),
( 9, 3, 'ACCOUNTS' ) ;
SELECT *
FROM @Table ;
SELECT *
FROM @Table AS s
WHERE AUTOID IN ( SELECT MAX(t.AUTOID) AS mx
FROM @Table AS t
GROUP BY t.RNO ) ;
