Mysql ODBC:未找到数据源名称，未指定默认驱动程序

我正在尝试连接到本地lan上的sql server，但不断出现以下错误

sqlTest:[Microsoft][ODBC驱动程序管理器]未找到数据源名称，也未指定默认驱动程序

我使用JRE 1.6 u27在Windows7 x64上以管理员身份运行SQuirreL SQL客户端版本3.2.1

我尝试连接到ubuntu 10.04上的SQL server 5.1

我的连接设置

不确定是url还是什么。另外，我在wireshark监视时尝试连接，但它没有接收到任何数据包。

是否要使用ODBC-JDBC网桥

我认为您应该使用本地JDBC驱动程序。如果您使用MySQL，则将字符串连接到数据库可能如下所示：

jdbc:mysql://10.11.12.1:3306/mybase

ODBC桥是用来连接ODBC数据源的，而不是MySQL（我想你说的SQLServer5.1就是这个意思）。
