正　文:

问:请问该数据库中的type列,怎么用查询,以逗号将该数据分割开
答:通过下面的自定义函数,结合查询来达到这一目的:
Function A(strType As String)
Dim x As Integer
x = InStr(strType, ",") - 2
A = Mid(strType, 2, x)
End Function
Function B(strType As String, strType2 As String)
    Dim x As Integer
    Dim typeTemp As String
    typeTemp = Mid(Replace(strType, strType2, ""), 3)
    x = InStr(typeTemp, ",") - 2
    If x > 0 Then
        B = Mid(typeTemp, 2, x)
    Else
        B = Mid(typeTemp, 2)
    End If

End Function
Function C(strType As String, strType2 As String, strType3 As String)
    Dim x As Integer
    Dim y As Integer
    Dim typeTemp As String
    x = Len(strType2 & strType3) + 6
    typeTemp = Mid(strType, x)
    y = InStr(typeTemp, ",") - 1
    If y > 0 Then
        C = Mid(typeTemp, 1, y)
    Else
        C = Replace(typeTemp, """", "")
    End If

End Function
Function strD(strType As String, strType2 As String, strType3 As String, strType4 As String)
    Dim x As Integer
    Dim typeTemp As String
    x = Len(strType2 & strType3 & strType4) + 6
    typeTemp = Mid(strType, x)
    strD = Mid(typeTemp, 2)

End Function
