在学生表STUD中，查询年龄在20至23岁之间的学生的姓名(XM)、年龄(SA) 和所在系(SD) ，实现该功能的正确SQL语句是( )。

SELECT XM，SA，SD FROM STUD WHERE BETWEEN 20＜SA＜23；

SELECTXM，SA，SD FROM STUD WHERE SA：BETWEEN 23 AND 20；

SELECTXM，SA，SD FROM STUD WHERE SA NOTBETWEEN20 AND 23；

SELECTXM，SA，SD FROM STUD WHERE SA BETWEEN 20 AND 23；

举一反三

【单选题】有如下事件过程：Private Sub Form_Load() Show Dim Arr() As Variant Arr = Array(1, 3, 5, 7, 9, 11, 13, 15) Call converse(Arr) For i = 0 To 7 Print arr(i); Next iEnd Sub 以上程序的功能是，通过调用Converse过程，将数组Arr中的元素逆序存放并输出...

Private Sub converse(dim a() as Variant ) Dim T For i = LBound(A) To UBound(A) T = a(i) a(i) = a(UBound(A) - i) a(UBound(A) - i) = T Next i End Sub

Private Sub converse(dim a() as Variant) Dim T Dim J As Integer J = (LBound(A) + UBound(A)) / 2 For i = LBound(A) To J T = a(i) a(i) = a(UBound(A) - i) a(UBound(A) - i) = T Next i End Sub

Private Sub converse(a() As Variant) Dim T For i = LBound(A) To UBound(A) T = a(i) a(i) = a(UBound(A) - i) a(UBound(A) - i) = T Next i End Sub

Private Sub converse(a() As Variant) Dim T Dim J As Integer J = Int((LBound(A) + UBound(A)) / 2) For i = LBound(A) To J T = a(i) a(i) = a(UBound(A) - i) a(UBound(A) - i) = T Next i End Sub
