Get Data from one DataSet to another Dataset

Hallo,
is it posible to get the date from dataset A to dataset B?

Here a short example to explane my problem:

Example
dataset A:
select a from tableA where b = ?

dataset B:
select * from A where A.a = ?

I have grouping based on dataset A, and dataset B is used internal in group.
In second dataset how can I link input "A.a" with the output "a" of dataset A?

Any help in this is much appreciated.
Thanks
danhof

Are you nesting tables with these datasets? If you are it is possible to use the row._outer["outercolumn"];

If you are nesting 2 tables, you could also use the Parameter binding feature on the Binding tab of the internal table to link the internal table to the outside table.
