OpenAccess SDK SQL engine is responsible for parsing SQL code, planning the execution, and supporting the data source interface.
OpenAccess SDK SQL engine layers complete SQL processing functionality on top of your data source. When configured for SQL pass-through mode, OpenAccess SDK SQL engine can be used to add SQL parsing capability while using the data source’s execution engine. OpenAccess SDK SQL engine implements a large portion of the entry level SQL as defined in the X3.135-1992,"Database Language SQL" specification and SQL features from ANSI SQL99 and commercial databases like SQL Server and Oracle. Please refer to OpenAccess SDK SQL Reference for the specific SQL that is supported by OpenAccess SDK SQL engine.
