1.安装mysql,

2.安装MyODBC-standard-3.51.07-win.msi

3:vb连接语句是:

Public strcnn As StringPublic sql As String

Public conn As New ADODB.Connection

Public rs As New ADODB.Recordset

Sub link()

strcnn = "driver={MySQL ODBC 3.51 Driver};server=localhost;database=data;uid=root;pwd=zjb"conn.Open strcnn

End Sub

错误MySQL 返回: #1251 - Client does not support authentication protocol requested by server; consider upgrading MySQL client

出现这种问题也只有在MYSQL4.1.x以上版本,用4.0.x就没问题了。

原因是因为使用的mysql服务器版本中使用了新的密码验证机制,这需要客户端的版本要在4.0以上,原来的密码函数被改为old_password ();,这样使用password()生成的密码在旧的版本上的客户端就不好使了,而PHP中的MYSQL客户端都是3.23的(当然,mysqli的扩展除外),问题就在这了。

1、进入命令行下,转到MYSQL目录的BIN目录下,进入MYSQL命令行模式:

例:d:\mysql\bin>mysql -uroot -p123 用户root,,密码123)

2、输入命令:mysql>set password for 'root'@'localhost'=old_password('123'); (注意冒号不能少)

3、退入MYSQL命令行:mysql>q

ok

linux
