完全自动化的SQL Server还原
我不太熟悉SQL Server命令。
我需要一个脚本来从.bak文件恢复数据库并将logical_data和logical_log文件移动到特定的path。
我可以：
restore filelistonly from disk='D:\backups\my_backup.bak' 这将给我一个列LogicalName的结果集，接下来我需要在恢复命令中使用结果集中的逻辑名称：
restore database my_db_name from disk='d:\backups\my_backups.bak' with file=1, move 'logical_data_file' to 'd:\data\mydb.mdf', move 'logical_log_file' to 'd:\data\mylog.ldf'
如何将第一个结果集中的逻辑名称捕获到可以提供给“move”命令的variables中？
我认为解决scheme可能是微不足道的，但我是SQL Server的新手。
这里是全自动恢复T-SQL存储过程。 接受三（3）个参数。
- 目标数据库
- 源数据库
- 完全限定的备份文件名称位置
（\\yourserver\yourshare\backupfile.bak或简单的c:\backup.bak）

RESTORE FILELISTONLY生成MSDN中logging的结果集。 然后你需要迭代这个结果集并构build一个合适的RESTORE … MOVE …如何捕获和迭代结果集取决于你的环境。 在C＃应用程序中，您将使用SqlDataReader。 在纯粹的T-SQL中，你可以使用INSERT … EXEC 。
纯SQL解决scheme的骨架将是：
declare @filelist table (LogicalName nvarchar(128), PhysicalName nvarchar(260), Type char(1), FilegroupName varchar(10), size int, MaxSize bigint, field int, createlsn bit, droplsn bit, uniqueid uniqueidentifier, readonlylsn bit, readwritelsn bit, backupsizeinbytes bigint, sourceblocksize int, filegroupid int, loggroupguid uniqueidentifier, differentialbaselsn bit, differentialbaseguid uniqueidentifier, isreadonly bit, ispresent bit, tdethumbprint varchar(5)); insert into @filelist exec sp_executesql N'restore filelistonly from disk=''D:\backups\my_backup.bak'''; set @sql = N'RESTORE database my_database from disk ''D:\backups\my_backup.bak'' with '; select @sql = @sql + N' move ' + LogicalName + N' to ' udf_localFilePath(PhysicalName) + N',' from @filelist; set @sql = substring(@sql, 1, len(@sql)-1); -- remove last ',' exec sp_executesql @sql;
这不是实际的工作代码，只是为了让你的想法。 您也可以使用游标来代替@sql的非标准的分配内部查询结构
请注意RESTORE FILELISTONLY的结果集中的列的列表在SQL Server版本之间是不同的。 请参阅目标版本规格以获取正确的列表。

我有同样的问题，但在我的环境中，我有很多备份文件（更快的备份），并需要恢复到自定义位置。 此查询获取最新的完整备份信息并恢复到您指定的path。 在SQL 2005/2008上testing

没有一个版本包含SQL 2000.这将适用于所有这些：

这可能有帮助。 我想为客户端创build一个脚本，并且需要为从单个位置恢复的多个数据库备份设置最小variables。 我试图避免使用dynamicSQL，因为我觉得这一切都变得有点混乱。

又一个修改/实现。 这是我的2美分。 我已经修改了上面的Mevdiven的脚本，以便它将文件恢复到当前的数据库数据目录。 我有一个问题，我不想使用备份文件中定义的位置。
我抓住第一个主文件使用的数据目录
SELECT top(1) @v_strRestorePath = physical_name FROM sys.master_files
并将其用作我的目标数据path。
我还发现## FILE_LIST表是悬挂的，所以我把它放在最后。

不知道如何添加评论下一个特定的解决scheme，但我刚刚实施的Mevdiven上面提供的解决scheme…
在我的环境（服务器08 r2）中的drop table有一个小问题。 我不得不修改这个使用对象id为了成功地下降。
由于备份文件中有大量的分区，我也有问题，所以我不得不将string更改为nvarchar（MAX）。
我还增加了将数据库恢复到另一个目录的能力（因为我们的开发和生产环境有不同的path）

This is a link to a framework for automating SQL database restores. It can help to initialize database mirroring and availability groups, execute test restores to verify production backup file integrity, implement a basic log shipping solution and to perform side by side upgrades. Recovery to history points in time is also possible, restores are optimized using the appropriate full, diff, log backups.
