SQL Server2005学习笔记一

SQLCMD Utility
sql command是微软一个win32控制台命令工具，它可以运行及时查询sql语句和脚本。它代替了sql server2000和以前的osql，isql等命令，可以参考这里的帮助http://www.588188.com/netbook/sqlserver2000/coprompt/cp_osql_1wxl.htm，http://www.588188.com/netbook/sqlserver2000/coprompt/cp_isql_8r39.htm。大家如果用过oracle中的sql*plus的话，就会明白这个工具的用途了。它的图形化工具在以前版本就是查询分析器了，现在在Yukon中用强大的带有开发调试集成的sql server管理中心，叫sql server manager studio.看微软的产品，都是用studio命名，这决定了他在软件领域的功能，业务，技术，开发的强大集成。Yukon中还有一个用于BI的business intelligence develop studio,以前有visual stuio 6.0,现有visual studio 2005,好了，转入主题。
首先这是个console命令
进入cosole的command Prompt，使用sqlcmd ＋参数等命令，可以连接上server 实例，数据库，运行sql和运行script file，将运行结果到处等
