Convert row to comma separated column


I have a table in oracle

Name    Task
------     ------
A           1
B           2
B           3
B           4
C           5
D           6
C           7

I want the output in following format

Name     Task
A            1
B            2,3,4
C            5,7
D            6

Can i get it in a single SQL without using any user function.

It's better to place your question to DB->Oracle
I think there is no aggregate function that would do this using a single SQL statement.
To obtain the desired output, you need to process data using a cursor and some temporary variables.
