Hi, is there a way to merge two datasets from two dataset in a third dataset. ?

Ex:

I have a datasource of Informix, then, I have a dataset from this dataset.

And I hava the second datosource of mysq, and a dataset.

I need to merge both dataseta in other dataset, and then this third dataset will be used in a table..

I suggest using a Join Dataset in BIRT Designer. This Joined Dataset will act like a 3rd Dataset. You obviously need a key to join the 2 Datasets.

Note : as the join is in your webapp memory, this might have some impact on performance.

Solution : Actuate Information Objects EII technology can efficiently parralelize and optimize these queries.

What if I have 2 key or more to join the dataset? Can it still be done?

mos,

You wouldn't be able to join your two datasets using just 1 of your keys?

Thanks scaracas, yes, I'm using a Join Dataset, and only a field to get union.

Thanks.
