mysql - 为什么连接字符串仅在开发机上工作？

我已经编写了2个程序，一个在VB6中，一个在VBA for Excel中。仅在开发机器上，调用mySQL连接都可以完美地工作。尝试在任何其他计算机上运行这两个程序失败。代码如下：

Private Sub cmdErrors_Click()
On Error GoTo remote_err

Set myCon = New ADODB.Connection
strConnect = "Driver={MySQL ODBC 5.3 ANSI
Driver};Server=xxx.xxx.xxx.xxx;Port=3306;Database=cl22-budget;User=username;
Password=password;Option=3;"

myCon.ConnectionString = strConnect
myCon.Open
MsgBox "Connected"
myCon.Close
Set myCon = Nothing
Exit Sub

remote_err:
Dim ErrorCollection As Variant
Dim ErrLoop As Error
Dim strError As String
Dim iCounter As Integer

On Error Resume Next

iCounter = 1
strError = ""
Set ErrorCollection = myCon.Errors
For Each ErrLoop In ErrorCollection
With ErrLoop
   strError = "error # " & iCounter & vbCrLf
   strError = strError & "ADO Error # " & .Number & vbCrLf
   strError = strError & " Description " & .Description & vbCrLf
   strError = strError & " Source " & .Source & vbCrLf
   MsgBox strError
   iCounter = iCounter + 1
End With
Next
End Sub

最佳答案

安装ODBC驱动程序并为您的数据库创建一个DSN，在其中您提到服务器IP的地方将询问服务器地址，然后它将起作用。
