vba 链接mysql

可以使用ADODB对象来链接MySQL数据库。首先需要安装MySQL ODBC驱动程序，然后在VBA中使用ADODB对象调用驱动程序来链接MySQL服务器。以下是一个简单的示例代码：

Sub ConnectToMySQL()
    Dim conn As New ADODB.Connection
    Dim rs As New ADODB.Recordset
    Dim server As String, user As String, password As String, database As String
    
    '设置链接信息
    server = "localhost"
    user = "root"
    password = "password"
    database = "db_name"
    
    '链接MySQL
    conn.ConnectionString = "Driver={MySQL ODBC 5.3 Driver};Server=" & server & ";Database=" & database & ";Uid=" & user & ";Pwd=" & password & ";Option=3;"
    conn.Open
    
    '查询数据
    rs.Open "SELECT * FROM table_name", conn
    Do While Not rs.EOF
        Debug.Print rs.Fields("field_name").Value
        rs.MoveNext
    Loop
    
    '关闭链接
    rs.Close
    conn.Close
End Sub

请注意，您需要将上述代码中的服务器，用户名，密码和数据库名称替换为您自己的实际值。
