DECLARE @table1 TABLE ( id VARCHAR(50) )
DECLARE @table TABLE ( id1 INT,id VARCHAR(50) )
INSERT INTO @table (id1,id) values (1, 'JOHN,rom')
INSERT INTO @table (id1,id) values (2,'Micky,Raju')
INSERT INTO @table (id1,id) values (2,'Micky,Raju')
INSERT INTO @table (id1,id) values (2,'Micky,Raju')
DECLARE @Min INT,@Max INT ,@str1 VARCHAR(100),@str2 VARCHAR(100)

DECLARE @x INT = 0
DECLARE @firstcomma INT = 0
DECLARE @nextcomma INT = 0

SELECT @x =   LEN(id) - LEN(REPLACE(id, ',', '')) + 1 from @table -- number of ids in id_list

WHILE @x > 0
    BEGIN
        SELECT @nextcomma =  CASE WHEN CHARINDEX(',', id, @firstcomma + 1) = 0
                              THEN LEN(id) + 1
                              ELSE CHARINDEX(',', id, @firstcomma - 1)
                         END FROM @table
                         --select @nextcomma
        INSERT  INTO @table1
        SELECT  ( SUBSTRING(id, @firstcomma + 1, (@nextcomma - @firstcomma) - 1) ) FROM @table 
        SELECT @firstcomma = CHARINDEX(',', id, @firstcomma + 1)FROM @table
        SET @x = @x - 1
    END

SELECT  DISTINCT id,COUNT(id)
FROM    @table1
GROUP BY id
