Does oracle have similar functionality like MsSql "for xml path('')"

Question

Does oracle have similar build in functionality like MsSql “for xml path(‘’)” , or in another word, it can enforce the result set(multiple rows) into ONE line such kind of presentation way.
Thanks in advance. Any help would be greatly appreciated.

Answer 1

Here I would like specify my question mnore clearly,
CREATE TABLE t(
line NUMBER(3),
site VARCHAR2(4),
phase VARCHAR2(5),
test VARCHAR2(25));
INSERT INTO t VALUES (1, '0100', '*','1111111111111111111111111' );
INSERT INTO t VALUES (2, '0100', '=','2222222222222222222222222' );
INSERT INTO t VALUES (3, '0100', '=','3333333333333333333333333' );
INSERT INTO t VALUES (4, '0100', '*','4444444444444444444444444' );
INSERT INTO t VALUES (5, '0100', '=','5555555555555555555555555' );
INSERT INTO t VALUES (6, '0200', '*','6666666666666666666666666' );
Here I want to retrieve the 'line' column information in ONE line way
select line from t I want the result is like '1,2,3,4,5,6'
Any generous help would be greatly appreciated!!!
