Join expressions, expressed in terms of objects, are translated into a relational database join statement by generating a parse tree based on the join expression. The parse tree is traversed to build the relational database join statement.

Translation of object queries involving inheritence

The select list for the query is thus constructed such that it produces a result set having a predefined structure. Columns representing identifier properties of an entity are added to the select list. If the entity is an inheritance entity or a collection, then entities from a least derived entity to all descendants are identified and columns representing their identifiers are added to the select list and columns representing non-inherited properties for those entities are added. If the entity is not an inheritance entity or a collection, then columns representing properties of the entity are added to the select list.
