MainTable mainTable;
SubTable subTable;
SubSubTable subSubTable;

while select mainTable

Link copied!

1) your child tables' subqueries looks like this:

1,2,3 notexists 1,2,3 = empty recordset.

2) parent table against subqueries:

1,2,3,4 notexists empty recordset = 1,2,3,4

I think what you meant is to link your second sub-table against the main datasource instead.
