在ASP中连接MySQL数据库有多种方法，以下是常见的两种方法：
1. 使用ADODB连接对象（ActiveX Data Objects）
```asp
<%
Dim conn, rs
Set conn = Server.CreateObject("ADODB.Connection")
conn.Open "DRIVER={MySQL ODBC 8.0 Unicode Driver};SERVER=localhost;DATABASE=mydatabase;USER=username;PASSWORD=password;OPTION=3;"
Set rs = Server.CreateObject("ADODB.Recordset")
rs.Open "SELECT * FROM tablename", conn
While Not rs.EOF
Response.Write(rs("columnname") & "
")
rs.MoveNext
Wend
rs.Close
Set rs = Nothing
conn.Close
Set conn = Nothing
%>
```
2. 使用MySQL Connector/ODBC驱动程序
```asp
<%
Dim conn, rs
Set conn = Server.CreateObject("ADODB.Connection")
conn.Open "DSN=mydsn;UID=username;PWD=password;"
Set rs = Server.CreateObject("ADODB.Recordset")
rs.Open "SELECT * FROM tablename", conn
While Not rs.EOF
Response.Write(rs("columnname") & "
")
rs.MoveNext
Wend
rs.Close
Set rs = Nothing
conn.Close
Set conn = Nothing
%>
```
请注意，上述代码中的参数（如服务器地址、数据库名称、用户名、密码等）需要根据实际情况进行修改。
