  Set Master property for detail query, use param names in the detail query as field names in the master dataset

  Where? On the Data tab? A short example would be great.

  Actually, I'm trying to do this from the Code tab, with something like this:
  

  begin
      GetDataSet('Product').MasterSource:=GetDataSet('Typ_prod').DataSet;                                                                                                                                                                                                                                                                                      
  end.
  

  
  But that doesn't work.

  But we're using dBase tables with TTable, not ADO.

  This is the same demo, with TfrxADOTable.

  There are no any differences between TfrxADOTable and TfrxBDETable usage

  I'd like to be able to use the designer to establish a master-detail relationship between a pair of TfrxBDETables. A TfrxADOTable can easily be dropped on the TfrxDesigner.CodePanel by using the palette. But TfrxBDETable is not available to be dropped. Can I get CodePanel to take a TfrxBDETable via code?

  Sorry, I meant I'm trying to add a TfrxBDETable to the DataTree. Something like "myBDETable.Parent:=TfrxDesignerForm(frxReport1.Designer).DataTree.DataPn;".

  Ok, this is a bit weird. Don't know why I didn't notice this before. The reason I've been asking about this is because I don't see the frxBDE components on the palette for me to add. Please check the attached screenshot named "NoBDE.png".
