TLzJoin = class(TLz_node);
Elements in from clause were represented by one or more TLzJoin objects.
Theta joins, which use the WHERE clause to establish the filtering criteria, are the "old" way to do join operations.
In such type of join, each table in from clause have a corresponding TlzJoin object with JoinTableType = jttNone
