[SQLSERVER] [RESTORE] 逐步恢复日志备份并使用只读模式查看

以下代码中，所有红字均需要替换为实际场景代码。执行：

USE master
GO

declare @dest_db NVARCHAR(max) = N'DbName'
declare @standby_file NVARCHAR(max) = N'C:可写路径Standby.standby'
declare @logical_datafile NVARCHAR(max) = 'Db' 
declare @logical_logfile NVARCHAR(max) = 'Db_log' 
declare @dest_datafile NVARCHAR(max) = N'C:Program FilesMicrosoft SQL ServerMSSQL12.MSSQLSERVERMSSQLDATADb.mdf'
declare @dest_logfile NVARCHAR(max) = N'C:Program FilesMicrosoft SQL ServerMSSQL12.MSSQLSERVERMSSQLDATADb_log.ldf'

--Restore full backup
RESTORE DATABASE @dest_db
 FROM DISK = N'\全量备份路径.bak'
 WITH REPLACE, STANDBY = @standby_file, move @logical_datafile to @dest_datafile, move @logical_logfile to @dest_logfile 
 
--Restore optional differential backup
RESTORE DATABASE @dest_db
 FROM DISK = N'\增量备份路径.dif'
 WITH STANDBY = @standby_file, move @logical_datafile to @dest_datafile, move @logical_logfile to @dest_logfile 

--Restore optional transactional log backup
RESTORE DATABASE @dest_db FROM DISK = '\日志备份路径.trn' WITH STANDBY = @standby_file, move @logical_datafile to @dest_datafile, move @logical_logfile to @dest_logfile 

此时数据库处于 Standby / Read-Only 模式

最后若要使其上线，执行：

restore database DbName with recovery
