How to restore to a different database in sql server?

Question

I have a backup of Database1 from a week ago. The backup is done weekly in the scheduler and I get a .bak file. Now I want to fiddle with some

Answer 1

If no database exists I use the following code:

ALTER PROCEDURE [dbo].[RestoreBackupToNewDB]    
         @pathToBackup  varchar(500),--where to take backup from
         @pathToRestoreFolder  varchar(500), -- where to put the restored db files 
         @newDBName varchar(100)
    AS
    BEGIN

            SET NOCOUNT ON
            DECLARE @fileListTable TABLE (
            [LogicalName]           NVARCHAR(128),
            [PhysicalName]          NVARCHAR(260),
            [Type]                  CHAR(1),
            [FileGroupName]         NVARCHAR(128),
            [Size]                  NUMERIC(20,0),
            [MaxSize]               NUMERIC(20,0),
            [FileID]                BIGINT,
            [CreateLSN]             NUMERIC(25,0),
            [DropLSN]               NUMERIC(25,0),
            [UniqueID]              UNIQUEIDENTIFIER,
            [ReadOnlyLSN]           NUMERIC(25,0),
            [ReadWriteLSN]          NUMERIC(25,0),
            [BackupSizeInBytes]     BIGINT,
            [SourceBlockSize]       INT,
            [FileGroupID]           INT,
            [LogGroupGUID]          UNIQUEIDENTIFIER,
            [DifferentialBaseLSN]   NUMERIC(25,0),
            [DifferentialBaseGUID]  UNIQUEIDENTIFIER,
            [IsReadOnly]            BIT,
            [IsPresent]             BIT,
            [TDEThumbprint]         VARBINARY(32) -- remove this column if using SQL 2005
            )
            INSERT INTO @fileListTable EXEC('RESTORE FILELISTONLY FROM DISK ='''+ @pathToBackup+'''')
            DECLARE @restoreDatabaseFilePath NVARCHAR(500)
            DECLARE @restoreLogFilePath NVARCHAR(500)
            DECLARE @databaseLogicName NVARCHAR(500)
            DECLARE @logLogicName NVARCHAR(500)
            DECLARE @pathSalt uniqueidentifier = NEWID()

            SET @databaseLogicName = (SELECT LogicalName FROM @fileListTable WHERE [Type]='D') 
            SET @logLogicName = (SELECT LogicalName FROM @fileListTable WHERE [Type]='L')           
            SET @restoreDatabaseFilePath= @pathToRestoreFolder + @databaseLogicName + convert(nvarchar(50), @pathSalt) + '.mdf'
            SET @restoreLogFilePath= @pathToRestoreFolder + @logLogicName + convert(nvarchar(50), @pathSalt) + '.ldf'

            RESTORE DATABASE @newDBName FROM DISK=@pathToBackup     
            WITH 
               MOVE @databaseLogicName TO @restoreDatabaseFilePath,
               MOVE @logLogicName TO @restoreLogFilePath

            SET NOCOUNT OFF
    END
