SELECT Child
SET RELATION field INTO Parent

I want to display all records in child table in the listbox if Parent record is moved.

E.g
Parent.field_x = "ABCDE"
I want to display all child.field_x = "ABCDE" in the listbox.

I've thousands record in child table and I can do that with SQL command, but very slow. I don't want to use Grid!

Thanks
