SQLServer笔记

1、还原数据库源不能有中文路径

2、JDBC连接非默认实例jdbc:jtds:${jdbc.db}://${jdbc.ip}:${jdbc.port};instance=IMS       ( net.sourceforge.jtds.jdbc.Driver)

创建备份设备
EXEC sp_addumpdevice 'disk', 'om_backup', 'D:\DataBase\Backup\om.bak'
EXEC sp_addumpdevice 'disk', 'ims_backup', 'D:\DataBase\Backup\ims.bak'
EXEC sp_addumpdevice 'disk', 'imsparam_backup', 'D:\DataBase\Backup\imsparam.bak'
EXEC sp_addumpdevice 'disk', 'imsstore_backup', 'D:\DataBase\Backup\imsstore.bak'
EXEC sp_addumpdevice 'disk', 'wf_backup', 'D:\DataBase\Backup\wf.bak'
备份数据库
BACKUP DATABASE om TO om_backup
BACKUP DATABASE ims TO ims_backup
BACKUP DATABASE imsparam TO imsparam_backup
BACKUP DATABASE imsstore TO imsstore_backup
BACKUP DATABASE wf TO wf_backup
还原数据库
RESTORE DATABASE om FROM om_backup
RESTORE DATABASE ims FROM ims_backup
RESTORE DATABASE imsparam FROM imsparam_backup
RESTORE DATABASE imsstore FROM imsstore_backup
RESTORE DATABASE wf FROM wf_backup

3、删除重复数据 delete   YourTable   where   [id]   not   in   ( select   max([id])   from   YourTable   group   by   (name   +   value))
