数据库表复制：

select * into xngzf.dbo.tb_qx_action from Smlw.dbo.tb_qx_action

drop table tb_qx_department;

mssql 追加行号 row_number()的用法

? 在使用查询结果的时候需要生成一个新的行号用来做统计，oracle 中有这个功能，mssql 用得很少不清楚有没有这项功能，

搜索了一下，网上的解决方法乱七八糟，有限竟然需要一张临时表，我汗，最后发现了一个比较好的解决方法，row_number()

select row_number() over(order by tablename.id) as row_number,* from tablename
