Abstract
Disclosed herein are system, method, and computer program product embodiments for eliminating redundancy when generating intermediate representation code. An embodiment operates by traversing a query execution plan, and for at least one operator in the query execution plan, determining whether the operator is derived from a parent class operator. If it is determined that the operator is derived from the parent class operator, source code for the native access plan is generated using one or more code generator functions corresponding to the parent class operator and/or one or more generator functions specifically corresponding to the child class operator. If it is determined that the operator is not derived from the parent class operator, source code for the native access plan is generated using one or more code generator functions corresponding to the operator.
