BIRT Report - group tables with different data
I am new to BIRT and I can't really figure out how Data Binding works. I need your help :) I have two tables that need to be linked (Element(s) with Sub Element(s)) and create groups of tables depending on how many elements and Sub Elements I have. There is an ID on each table to join them(BOBJECT_ID in Elements is equals with BOBJECT_ID in Sub Elements). Scenarios: I can have 1 Element with 0 or N Sub Elements I can have N Elements with 0 or N Sub Elements each To give more infos, here is an example: 1 Element with 11 Sub Elements This is an example in case there is only one Element - The Element 1 is represented in the first table and the second table represents the Sub Elements of the Element 1. In case there is another Element with Sub Elements, I need to create another 2 tables exactly like this one with the corresponding data. If I have 10 Elements each one with 5 Sub Elements, I have to create 10 groups of the 2 tables with each Element and his 5 Sub Elements. Thank you!
Depending on what solution you decide you'll need tow tables or just one table. two possiblities: "Table in Table" Create Dataset for outer data Create Dataset for inner sub-data Create one Table for outer data and add a second "Details Row" Create second Table nested in the second "Details Row" Filter this second Table to show only entries with outer row's ID "Joined Dataset / Grouping on Table" Create a Joined Dataset Create one Table looping on that data Add Grouping to that one Table
