数据库备份遇到的问题

1、没有数据库时先创建一个同名数据库，然后选择备份，此时需要全备份，分量备份不可以

     如果都正常操作还提示“备份集中的数据库备份与现有不同”则用语句执行

RESTORE DATABASE workpointmanage_sass
FROM DISK = 'C:\Program Files\Microsoft SQL Server\MSSQL10_50.MSSQLSERVER\MSSQL\Backup\workpointmanage_sass_datafull_201412040742_12040742.bak'   --bak文件路径
with replace,
MOVE 'workpointmanage_sass' TO 'C:\Program Files\Microsoft SQL Server\MSSQL10_50.MSSQLSERVER\MSSQL\DATA\workpointmanage_sass.mdf',   --mdf文件路径
MOVE 'workpointmanage_sass_log' TO 'C:\Program Files\Microsoft SQL Server\MSSQL10_50.MSSQLSERVER\MSSQL\DATA\workpointmanage_sass.ldf'   --ldf文件路径

2、数据库还原中提示数据库正在被占用，需要分离数据库再联机，手动操作无效时可用如下语句

declare @dbname varchar(20)

set @dbname='workpointmanage_sass'

declare @sql nvarchar(500)

declare @spid int--SPID 值是当用户进行连接时指派给该连接的一个唯一的整数

set @sql='declare getspid cursor for

select spid from sysprocesses where dbid=db_id('''+@dbname+''')'

exec (@sql)

open getspid

fetch next from getspid into @spid

while @@fetch_status<>-1--如果FETCH 语句没有执行失败或此行不在结果集中。

begin

exec('kill '+@spid)--终止正常连接

fetch next from getspid into @spid

end

close getspid

deallocate getspid
