SQuirreL SQL Client is a graphical Java program that will allow you to view the structure of a JDBC compliant database, browse the data in tables, issue SQL commands etc, see Getting Started and Introduction.

的确很好用，用java -jar squirrel.jar 运行安装，如果连接mssql的话，下载一个sqljdbc4.jar即可（Microsoft MSSQL Server JDBC Driver）

运行Squirrel后，Aliases是用来连接数据库的，执行sql...；Drivers是用来设置JDBC的驱动
