Hi,
I am creating some reports in BIRT, and my datasource is Jazz.
I have a situation that I am getting duplicated rows from my database table, and are show like this:
ID Name Year
-------------------------------
10 John 1983
10 John 1983
10 John 1983
11 Dany 1983
11 Dany 1983
12 Mark 1983
12 Mark 1983
etc etc...
when I count rows, I get, for example total 7 rows.
so, I want to remove duplicate rows, and get three different rows,
and count of them 3.
Actually, I would like to help about writing handler which will, for example, delete duplicate rows during rows creation.
P.S. I know I could resolve problem with sql disctinct, but unfortunately, sql is not supported yet in this Jazz version.
Thanks,
|

If you can't do it on the SQL side, then you need to group your report by ID, Name and Year, and only show the first group footer.
GROUP 1 HEADER: ID (suppress)
GROUP 2 HEADER: NAME (suppress)
GROUP 3 HEADER: YEAR (suppress)
DETAIL ROW ID ... NAME ... YEAR (suppress)
GROUP 3 FOOTER ID ... NAME ... YEAR
GROUP 3 FOOTER (suppress)
GROUP 3 FOOTER (suppress)
I think that will give you what you need.

If you are just using these in a birt table you could always just hide
the duplicate rows using script. If that is what you need let me know
and I will post an example.

To group by year (and you're not quite clear on how you want your output to look, so this is a best guess).
GROUP 1 HEADER: YEAR (visible)
GROUP 2 HEADER: NAME (suppress)
GROUP 3 HEADER: ID (suppress)
DETAIL ROW ID ... NAME ... YEAR (suppress)
GROUP 3 FOOTER ID ... NAME
GROUP 2 FOOTER (suppress)
GROUP 1 FOOTER (suppress)
There are probably at least a half dozen similar approaches. This gives you:
1983
10 John
11 Dany
12 Mark
