SQLServer數據庫常用操作命令

實現SQL Server 自增標誌列清零

dbcc checkident(tb_qx_resource, reseed, 0) 

數據庫表複製：

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

數據庫表刪除：

drop table tb_qx_department;

mssql 追加行號 row_number()的用法

  在使用查詢結果的時候需要生成一個新的行號用來做統計，oracle 中有這個功能，mssql 用得很少不清楚有沒有這項功能，

搜索了一下，網上的解決方法亂七八糟，有限竟然需要一張臨時表，我汗，最後發現了一個比較好的解決方法，row_number()

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