Nick,

you don't have to set it up as a master-detail relationship, you can do
it this way, too:

Use the OnDataChangEvent of the Datasource that's bound to the
MasterQuery and add sth. like:

procedure MyForm.DSOnDataChange ( ... )
begin
if Field = NIL then
begin
with detailQry do
begin
if not Prepared then Prepare;
Params[0].AsInteger := masterQry.FieldByName ( 'XX' ).AsInteger;
Open;
end;
end;
end;

this way you set up your own master-detail handling.

I forgot that the masterlinks-entry is providign a where clause, so this
shouldn't work with selecting from procedures, wehre you need an input
param.


Let me know if this suits you.

Luc.
