Hello, Newbie here. Is there a way that I can transpose DB rows into columns? I am thinking, that I can read the rows into a hashmap and then do some processing there, but am just not sure how to go about this.

For example: If I have the below table: 

 id name dept date_joined email date_sent
       1  P1    Test   12/10/14  Y    12/11/14 10:53:45
       1  P1    Test2  1/1/14    Y    1/05/14 05:25:34
       2  P2    Test  3/1/14  N    Null
       2  P2    Test   8/1/14  Y    8/05/14 11:28:28
       3  P2    Test3  10/1/14 N    Null

Desired Output is: 
   id   name  Test             Test2          Test3       Y_email  N_E
+mail
   1    P1   12/10/14,8/1/14  1/1/14,3/1/14 10/1/14  12/11/14 10:53:45
+,1/05/14 05:25:35,8/05/14 11:28:28  Null
   2    P2  1/1/14,3/1/14       null         10/1/14 Null, Null

Basically, trying to transpose and flatten it to get one row per recor
+d.

Any ideas how I can do this?

Can anyone suggest how I can go about this in the simplest way possible? The data I am dealing with is huge.

Thanks in advance
