Answer 1

Speaking from ancient history (i.e, over five years ago) the way master/detail was handled automatically with VCL datasets was by setting properties on associated TDatasource components. See here for an example: http://delphi.about.com/library/howto/htdbmasterdetail.htm

Otherwise just dynamically alter the WHERE clause in the SQL for the detail dataset, or set the Filter property on the detail dataset: http://docwiki.embarcadero.com/VCL/en/DB.TDataSet.Filter

If in the detail you set the datasource to the master then you can try using parameters in the detial that match a field in the master. So if in the master you have the following: SELECT field1, field2, field3 FROM table Then in the detail you have: SELECT d_field1, d_field2, d_field3 FROM detail WHERE some_field=:field1 So that the parameter 'field1' has the same name of a field (field1) returned from the master.
