Fully automated SQL Server Restore

Question

I\'m not very fluent with SQL Server commands.

I need a script to restore a database from a .bak file and move the logical_data and logical_log files to a specific p

Answer 1

/*
Automate restore w/o needing to know the logical file names.
Specify destination database name, database backup source filename
and .MDF, .LDF and .NDF directories.
I do nightly automated database restores,
and I've been using this code for about a month.
Works for sql server 2008, might work for 2005.

as references, I came up with this .. and I think it works (not tested for backups with multiple files)

DECLARE @FileList TABLE

 declare @RestoreStatement nvarchar(max), @BackupFile nvarchar(max);

 set @BackupFile = 'D:\mybackup.bak'

 SET @RestoreStatement =  N'RESTORE FILELISTONLY
      FROM DISK=N''' + @BackupFile + ''''

INSERT INTO @FileList
      EXEC(@RestoreStatement);

declare @logical_data nvarchar(max), @logical_log nvarchar(max);

set @logical_data = (select LogicalName from @FileList where Type = 'D' and FileID = 1)
set @logical_log = (select LogicalName from @FileList where Type = 'L' and FileID = 2)

I had same issue, but in my environment I have many backup files (faster backups), and did need to restore to custom location. This query gets latest full backup info and restores to the path you specify. Tested on SQL 2005/2008.

SET NOCOUNT ON

Declare @BackupFiles varchar(500), @data_file_path VARCHAR(512), @log_file_path VARCHAR(512), @RestoreFileList varchar(2000), @RestoreStatement varchar(3000), @MoveFiles varchar(2000), @DBName varchar(150)

DECLARE @filelist TABLE (LogicalName NVARCHAR(128) NOT NULL, PhysicalName NVARCHAR(260) NOT NULL, [Type] CHAR(1) NOT NULL, FileGroupName NVARCHAR(120) NULL, Size NUMERIC(20, 0) NOT NULL, MaxSize NUMERIC(20, 0) NOT NULL, FileID BIGINT NULL, CreateLSN NUMERIC(25,0) NULL, DropLSN NUMERIC(25,0) NULL, UniqueID UNIQUEIDENTIFIER NULL, ReadOnlyLSN NUMERIC(25,0) NULL , ReadWriteLSN NUMERIC(25,0) NULL, BackupSizeInBytes BIGINT NULL, SourceBlockSize INT NULL, FileGroupID INT NULL, LogGroupGUID UNIQUEIDENTIFIER NULL, DfferentialBaseLSN NUMERIC(25,0)NULL, DifferentialBaseGUID UNIQUEIDENTIFIER NULL, IsReadOnly BIT NULL, IsPresent BIT NULL, TDEThumbprint VARBINARY(32) NULL)

Answer 4

not sure how to add comments under a particular solution but I have just implemented the solution provided by Mevdiven above...

There is a slight problem with the drop table in my environment (Server 08 r2). I have had to modify this to use the object id in order to drop successfully.

I also had problems due to a large number of partitions in the backup file, so I had to change the string to be nvarchar(MAX).

I also added ability to restore the database into another directory (as our dev vs prod environments have different paths)
