Answer / sujatha nulu

Hi,
We have well advanced concepts in Oracle to achieve this.
LISTAGG analytical function can be used for this.

If its ename to be concatenated yet separated by delimiter,
use this way;

SELECT LISTAGG(ename,'|')
WITH IN GROUP (ORDER BY DEPTNO)
FROM EMPLOYEES
GROUP BY DEPTNO
ORDER BY DEPTNO;

You can write a procedure and pass column, delimiter as
parameters.
