Abstract
A suggested query execution plan is used as a constraint on a guided optimization process such that all execution plans that do not conform to the suggested execution plan are eliminated as possible alternatives. If the guided optimization process successfully generates a resulting execution plan, then the result will conform to the suggested execution plan. If the guided optimization process fails to generate a resulting execution plan, then it may be determined that the suggested execution plan is invalid.
