Python 环境:python3 服务器环境: centos6.5 数据库: Mysql 大概流程:在装有Python服务器,利用pymssql库连接MSSQL生产数据库取出数据然后写进mysql数据库里,再从mysql里取出需要的数据,制作对应的报表: SQLServer 权限:master只读权限,grant view server state to user,或者限定具体系统视图只读权限 贴出部分代码: 后续可以写成类,可以大大提高执行速度,不过此脚本执行频率不高. ##########
Select GETDATE() as '当前日期',DateName(year,GetDate()) as '年',DateName(month,GetDate()) as '月',DateName(day,GetDate()) as '日',DateName(dw,GetDate()) as '星期',DateName(week,GetDate()) as '周数',DateName(hour,GetDate()) as '时',DateName(minute,GetDate()) as '
SQLServer本身并没有提供随机读取记录的功能,但我们可以通过一些方法来实现这个目的.本文介绍了其中几种方法并比较了各自的优劣. 方法一:直接通过Sql语句实现,如: SELECT TOP 100 * FROM BCUSTOMER_MZN SELECT TOP 100 * FROM BCUSTOMER_MZN ORDER BY NEWID() 这是最简单的方法,通过调用SqlServer的newid()函数(产生GUID—全局唯一标志符)来产生随机记录.采用这种方法时,需要将表中所有记录与n
取众位数:先按个数倒排序,再取第一条SELECT * FROM ( select a.billid,a.DemandVoltage,count(1) as RecordCount, Row_NUMBER() OVER(PARTITION BY billid ORDER BY count(1) DESC) AS SN from ETL_SingleCharging201805 a with(nolock) WHERE RowKey LIKE '00000058-bca0-4559-8f8f-2fc
