How to add an extra row in data set after fetch

cypherdj

Hi there,

Basically, I want to join 2 queries, one containing all users, the other containing tasks per department.

Some tasks may be unassigned, in which case the userid is 0.

I then create a full outer join on the 2 queries, so for the purpose of the unassigned tasks, I'd like to insert a dummy user in the users data set.

Is it possible to insert an extra row after fetch or any other event?

Thanks,
Cedric

Hi Cedric,

I'm guessing that the easiest solution would probably just be to have a dummy user added to the user database for use with your report. If you aren't able to do that, you should be able to create a java based dataSource that runs an embedded SQL query on your database and then adds the dummy record to the end. So far, I don't see an easier way to do this within BIRT.

Thanks for the suggestions Michael, but adding the dummy row in the database is not an option, and using java is something I'd be reluctant to do.

I found another way to get round my problem, by adding the following to my original user query:

union
select 0 as userid,
'Unassigned' as username,
i as deptid,
name as deptname
from department

This effectively creates the dummy row in the result set for all departments at runtime. Not the most elegant, but does exactly what I want!

Cedric,

Yeah, that's definitely simpler than what I suggested. I didn't even think about that. Glad you found something.
