在执行预准备语句时，您需要为绑定的每个值#lang pl (require rackunit) (require racket/trace) ;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;; ;;Question 1 (: min&maxRec (-> (Listof Number) Number Number (Listof Number))) (: min&max (-> Number Number Number Number Number (Listof Number) )) (define (min&max number1 number2 number3 number4 number5) ; gets all numbers and sends to the min&max recursive part (min&maxRec (list number2 number3 number4 number5) number1 number1)) ; made all numbers to become a list and has max and min numbers (define (min&maxRec myList max min) ;; logic: 1) if finished list give back result 2) else check if head of list max or min and recall the function with a shorter list and the new max or min (if (null? myList) ;return the min and max from myList when finished looking at all numbers (list min max) (if (> (first myList) max); is the head max? (min&maxRec (rest myList) (first myList) min) (if (< (first myList) min) ; is the head min? (min&maxRec (rest myList) max (first myList) ) (min&maxRec (rest myList) max min))))) (test (min&max 2 3 2 7 1) => '(1 7)) ;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;; ;;Question 2 a (: sublist-numbers (-> (Listof Any) (Listof Number))) (: tail-sublist-numbers (-> (Listof Any) (Listof Number) (Listof Number))) ;;This func calls a diff func since the tail-recursion needs an accumelator. (define (sublist-numbers myList) (tail-sublist-numbers myList `())) ;;this uses tail-recursion (all calculations are dont before the recursion and are sent with an accumelator) (define (tail-sublist-numbers myList acc) (if (null? myList) acc ; if finished all vars in list (if (number?

看看使用knex.js模块这样的东西可能是值得的。它使用下面的mysql模块并在底层进行sql绑定。
