Generating a native access plan for dynamic entity calling

A system, comprising:

• a memory;
• and
• at least one processor coupled to the memory and configured to:
• receive a query execution plan comprising at least one run-time call to a function, wherein the function includes a plurality of different implementations;
• translate the run-time call to the function into a corresponding implementation of the function, for each of the plurality of different implementations, based on an identifier of the function;
• determine, from an address array of a first data structure, entry addresses for each of the plurality of implementations of the function as included in the query execution plan, wherein at least one of the plurality of implementations of the function for which an address has been determined is not called during run-time within the query execution plan;
• store the address array, including the addresses corresponding to the subset of the plurality of implementations of the function as included in the query execution plan, in a global variable at compile time;
• and
• generate source code of the native access plan that implements the query execution plan including the addresses of the address array.

A non-transitory computer-readable device having instructions stored thereon that, when executed by at least one computing device, causes the at least one computing device to perform operations comprising:

• receiving a query execution plan comprising at least one run-time call to a function, wherein the function includes a plurality of different implementations, translating the run-time call to the function into a corresponding implementation of the function, for each of the plurality of different implementations, based on an identifier of the function;
• determining, from an address array of a first data structure, entry addresses for each of the plurality of implementations of the function as included in the query execution plan, wherein at least one of the plurality of implementations of the function for which an address has been determined is not called during run-time within the query execution plan;
• storing the address array, including the addresses corresponding to the subset of the plurality of implementations of the function as included in the query execution plan, in a global variable at compile time;
• and
• generating, by the at least one processor, source code of the native access plan that implements the query execution plan including the addresses of the address array.
