Need function which accepts column name as a input and returns comma separated values in that column.

Hi All,

I need function which accepts column name as a input and returns comma separated values in that column.

CREATE TABLE [dbo].[EMP](

	[ENAME] [varchar](10) NULL,

	[HIREDATE] [datetime] NULL,

	[COMM] [numeric](7, 2) NULL,

SELECT * FROM EMP

I WANTED TO CREATE ONE FUNCTION WHICH ACCEPTS COLUMN NAME AS A INPUT PARAMEter
AND SHOULD RETURN ALL VALUES WITH IN THAT COLUMN BASED ON COMMA SEPARATED.
FOR EXAMPLE: 1
------------
If i pass ENAME(column name) as a input paramer to the function following output as to come
Output:
SMITH,ALLEN,WARD,JONES,MARTIN,BLAKE,CLARK,SCOTT,KING,TURNER,ADAMS,JAMES,FORD,MILLER

FOR EXAMPLE: 2
------------
If i pass EMPNO(column name) as a input paramer to the function following output as to come
Output:
-------
7369,7499,7521,7566,7654,7698,7782,7788,7839,7844,7876,7900,7902,7934

Thanks in advance.
