Help - how to add my own data to a table

Question

Hello,
I looked at the tutorials, but cannot get this to work.
I want to load a table (each row) with data I read from other tables.
I tried:
RowKey rk = objectArrayDataProvider1.appendRow();
FieldKey fk = new FieldKey("A");
objectArrayDataProvider1.setValue(fk,rk,"HELLO");
Can someone point me in the right direction with some good code?
Thanks
Frank

Answer 1

What I am trying to do is asemble data from three tables and add them to a datatable. Data may not be in all three tables, but all info from the first table must be added to the datatable.
table 1 has a list of procedures, these must be included.
table 2 has a list of providers
table 3 has a schedule that has date, procedure_id, provider_id.
I have to read table 3 for a given date, then add the provider if he is scheduled for a procedure.
Thanks
Frank
