Concate column into char in report builder

Question

Helllo!
I am working on a report in report builder 6.0.8.27.0 connected to a 10g database.
In my report i summarize a workers pick performance over a specified period of time on each new row (things like picks, active pick time). Most of the data is summarized using the in-built sum-function in report builder. But i have also a column in my table where i want to concate/aggregate the work zones(physical locations) that a worker has been in over a day.
A simplified example of how my input query table can look like:
user | picks | inlogged_time | work_zone
mav | 100 | 10 | AREA1
mav | 200 | 30 | AREA2
ant | 100 | 10 | AREA3
max | 100 | 10 | AREA3
This should generate a report that has this structure:
user | picks | inlogged_time | work_zone
mav | 300 | 30 | AREA1, AREA2
ant | 100 | 10 | AREA3
max | 100 | 10 | AREA3
My problem is i dont know how to concate the work_zones togheter. I tried using the PL/SQL editor for a function (using vm_concate()), but i could not get it to work and i can't use a new Select statement in my PL/SQL editor because the tables are to large for doing a new query on each row.
Grateful for any help!
Regards,
Martin

Hi,
A small modification to the above query ....
with data as ( select 'mav' username, 100 picks, 10 inlogged_time, 'AREA1' work_zone from dual union all
select 'mav' username, 200 picks, 30 inlogged_time,'AREA2' work_zone from dual union all
select 'ant' username, 100 picks, 10 inlogged_time, 'AREA3' work_zone from dual union all
select 'max' username, 100 picks, 10 inlogged_time, 'AREA3' work_zone from dual  )
select username, sum(picks) picks , sum(inlogged_time) inlogged_time , wm_concat(work_zone) work_zone
from  data
group by usernameOutput:
USERNAME,PICKS,INLOGGED_TIME,WORK_ZONE
'max','100','10','AREA3'
'mav','300','40','AREA1,AREA2'
'ant','100','10','AREA3'Regards,
