I set Query's Property DataSource for linking to Master Table,
such as: Query1.DataSource:=DataSource1.
But in running time, sometimes I want Query1 working independing.
Therefore I have to release this Master/Detail relation.
I wrote Query1.DataSource:='', and got compiler error.
Anyone can tell me how to define Query's property DataSource for a null source?
ps:When I define Query1.DataSource:=DataSource2,which DataSource2 point to nothing table.
And it is working, but I know it is not good method.
