sqlCmd下的备份还原执行sql脚本和事务等处理

SqlCmd -S ./SqlExpress

//备份等命令

 

      //控制单用户访问和多用户访问

      //USE [master]

      //GO

      //ALTER DATABASE [BidFileSell] SET  SINGLE_USER WITH ROLLBACK IMMEDIATE

      //ALTER DATABASE [BidFileSell] SET  MULTI_USER WITH NO_WAIT

      //GO

 

//备份恢复数据库

 

'说明，备份恢复数据库

SQLCMD -S ./sqlexpress -U sa -P 000000 -d master -Q"BACKUP DATABASE test to disk='c:

 

/aa/aaa.bak'"

SQLCMD -S ./sqlexpress -U sa -P 000000 -d master -Q"RESTORE DATABASE test from 

 

disk='c:/aa/aaa.bak'"

'说明 ，在D:下database文件夹，在database下建立data

sqlcmd -S ./sqlexpress -i c:/createtable.sql

'重复几次，5次

sqlcmd -S ./sqlexpress -i c:/createdata.sql
