请问老师：有没有【DUpdate】、【DInsert】函数。或者哪位老师写过这种函数。

仿照系统函数：Dlookup，Dsum，Dcount，Dmin
写了一个函数：DUpdate
请高手指点，能否优化！

Private Const SQL分隔符 = ","
Public Function DUpdate(字段串 As String, 数值串 As String, 记录集 As String,Optional  WHERE As String="") As String '返回SQL语句
DUpdate = ""
If 字段串 = "" Or 数值串 = "" Or 记录集 = "" Then Exit Function
On Error GoTo err
Dim 字段() As String, 数值() As String, STR As String
字段 = Split(字段串, SQL分隔符)
数值 = Split(数值串, SQL分隔符)
STR = ""
For i = LBound(字段, 1) To UBound(字段, 1)
    If i > UBound(数值, 1) Then Exit For '字段串与数值串 个数不一致。
    STR = "," & 字段(i) & "=" & 数值(i)
Next i
STR = "SET " & Mid(STR, 2) ' SET 子句
STR = "UPDATE " & 记录集 & " " & STR
If WHERE <> "" Then STR = STR & " WHERE " & WHERE '有WHERE语句！
Debug.Print STR 'SQL语句！
DoCmd.SetWarnings False '关闭警告提示
DoCmd.RunSQL STR
DoCmd.SetWarnings True   '打开警告提示
DUpdate = STR
Exit Function
err:
    MsgBox Error$
End Function
