Change BIP-based framework to adapt with the handling of INUM for NLJ and multiple-instances of a relation #315

Closed tqtrung closed 12 years ago

tqtrung commented 12 years ago

The old design of BIP-based framework (the QueryPlanDesc interface) assumes that at most one relation appears in a query. This interface and the corresponding BIP-based codes need to be revised in a general way to handle NLJ and multiple-instances of a relation in a query also.

The interface of QueryPlanDesc works well with DIV-BIP.
