Hi there,
i am new to dataface, seems to be very interesting, specually because some of my colleagues uses dataface.
I found at the beginners tutorial :
The WHERE clause of your SQL definition for the relationship must contain only '=' comparisons, and 'AND' conjunctions. i.e., it cannot receive an 'OR' conjunction, nor can comparisons be done using '>', or '<'. This is because given 'AND' and '=' conjunctions it is easy for dataface to be able to add records that will satisfy the relationship. If an 'OR' conjunction is used, it makes it ambiguous (though this will probably be corrected in future dataface releases.
Since i usually have database sets where this would be a severe restriction:
Will more flexible relationship-definitions possible in the future, and when?
