Andrey Razumovsky updated CAY-1235:
-----------------------------------

    Attachment: 1235.diff

This is my implementation of the feature. The only disadvantage I see is that we cannot provide different qualifiers for different DBMS. Personally I don't think this is too important by now. So, if there aren't any objections I will add modeler support and commit next week

> This is much like ObjEntities qualifier, only applied on DBEntities level. This, for instance, means that it will be inserted in needed JOINs of any select, thus allowing to use restricting qualifiers in e.g. middle table of many-to-many flattened relationship.
> This issue includes core changes and modeler support
