Summing up Data field values [message #149402]

All,

I'm new to BIRT and finding the report designer quite nice, and have had
relatively little trouble constructing my report and using queries to
populate the data. I'm creating a standard Income Statement that pulls
bottom-line data from at least three separate SQL queries. By bottom-line,
I mean that I'm letting the database give me the line items in total, not
having BIRT sum up large amounts of data.

What I'm up against is that I can't seem to get a total on the bottom of the
report. Using Total.sum() expects a row or some other expression that I'm
unable to figure out. What I kinda want is the ability to blindly sum up a
"virtual" column without caring where the data came from. I'll try to
exemplify this:

Query1.col1 $5
Query1.col2 $5
Query1.col3 $5
Query2.col1 $3
Query3.col1 $3
Total ????

I'm using a Grid to layout a 2-column arrangement for this and the actual
values in the right column are Data objects. Notice that multiple data
sources and columns are used. I can't just some up some single column from
a single data source. I need to sum up the Grid's second column.

Can anyone help?

Thanks in Advance,

Chris

Hi,

I have two suggestions for you:
1. Have you consider using UNION (or UNION ALL in oracle) for your
queries to join them together? You could add pseudo-column to your
queries to get to know which query your data comes from, or for grouping
purposes.

2. There is very interesting thread on this group

news://news.eclipse.org:119/dvuboo$jfp$1@utils.eclipse.org

where Scott Rosenbaum explains how to perform your own calculations over
subreports. If you don't like UNION than read this topic and you will
find the solution for sure.

I see the thread. I'll try out that technique and post up my results if it
proves helpful to the group.

Many thanks,

Chris
