Abstract
A system, method, and computer-readable medium for the calculation of execution time estimates of user defined functions/user defined methods are provided. The execution of a UDF or UDM is timed several times at the time of the UDF/UDM creation, and an average execution time of the UDF/UDM is obtained. The resulting average execution time is then stored in a data dictionary where the optimizer may consult this value to factor it into the cost of execution of a query.
