JavaScript能访问客户SQL数据库？能！（Access a client side MSSQL database by JavaScript）
JavaScript能访问客户SQL数据库？能！真的能！
要求：SQL Server2000（其它版本没试过）,且数据库必须安装了WMI扩展（WMI SQL Server Administration Provider，能在SQL Server2000安装光盘的"x86otherwmi" 目录下找到）
好了，接下来我们试试代码吧：（code from http://www.devarticles.com/c/a/JavaScript/Combining-North-Pole-with-South-Pole-JavaScript-with-SQL-Server-2000/）

呵呵，虽然也许没有什么实用价值，但JavaScript竟能访问SQL Server数据库，确实令人惊叹！
