HI. I just installed Seal Report to explore it's capability. The demo is very nice and it seems like a good start.
I have been able to create a data sources and access both oracle and sql server data bases, so I have a basic understanding of how it is working.

One of my needs is to combine information from multiple sources into a single report.
For instance, I have two distinct SQL Server databases and I need to combine data from both into a single display item in a report.

So far I have been unable to do this. What I found in the forum also suggests this is not supported, but the messages are fairly old.

Is this still true? any single report is restricted to a single source?

Thanks.

You can display different data sources in a report.
A report can contain Data Source 1 and Data Source 2
Then you can create Model 1 on Data Source 1 and Model 2 on Data Source 2
Then a View 1 displaying Model 1 and View 2 with Model 2


You just change the 'Source' property in 'Model Definition' when you edit your model.

And in the view of type Model, just change the 'Model' property.

Good luck.

Thanks for the info, but I think my wording was not specific enough, my bad.

I was able to do what you suggested: have two source, two models and see data from both in one view as two separate items.

What I want to do is combine the data from two sources to produce a new value for display in the report.

Here's what I am trying to do.

Source A has planned events with the projected results.

Source B has the current event status and up to the minute results.

I would like to display the current results (in Source B) as a percent of the projected results (from Source A).

Is this sort of thing possible in Seal Reports?

Thanks.

There are several ways to handle this:
- if you can, create a linked server to Oracle and query directly the SQL Server which will handle the joins and data got from Oracle
- use Seal Report Scripts: if you know C# and the SR Object model, it is quite easy to use the value got from one model to modify the table result generated for another model.
take a look at the sample 54-Final Script which shows how to modify the result table (Property 'Final Script' of the model).
You may use also the 'Cell Script' property of an element of your model to modify it.

Good luck.

Ok, thanks. I'll look into that sample.
