Query processing: with SQL pass-through

The OpenAccess SDK SQL engine can be used in a mode in which it parses the query but leaves the execution of the query to the IP. This mode of operation is ideal when the backend is capable of handling a querying language that may or may not be compatible with SQL but where the OpenAccess SDK SQL engine is required to expose a standardized SQL view. This mode can be used to add an additional WHERE constraint to all queries executed on an RDBMS. See Implementing SQL pass-through mode for more information.
