Remarks
What if there is more than one record with rank 1? Not a problem, the QueryProvider base class will detect and discard duplicate rows based on the query primary key. Which particular record survives is a matter of chance, but since they both have the same rank they're semantically equivalent, anyway.
InnerModifyQuery()
Template method called from ModifyQuery() during query processing; subclasses should implement it to build their queries. It will ONLY be called if
Declaration
protected abstract void InnerModifyQuery()ModifyQuery()

Declaration
public virtual void ModifyQuery()SetJoin()
Subclass contract: Implementations of this method should create the extenders' table information object, join it to the relevant parent, and return the table information instance
