Good Morning.
I am writing a backup script and getting the following error message:
Msg 137, Level 15, State 2, Line 7
Must declare the scalar variable "@ arquivo_DIF."

It is a script to restore FULL and Differential Backups.
If run the backups work separately, but the script is giving this error.

code position below:

Declare @pasta char(3),
        @arquivo_FULL varchar(255),
        @arquivo_DIF varchar(255),
        @caminho varchar(255)

set @pasta = case datepart( dw, getdate() )
                  when '1' then 'Dom' when '2' then 'Seg' when '3' then 'Ter' when '4' then 'Qua'
                  when '5' then 'Qui' when '6' then 'Sex' when '7' then 'Sab'
             end

set @caminho = 'T:\Backup\' + @pasta + '\'

set @arquivo_FULL = @caminho + 'bkpFULL_'+ 'db1' + '_' + @pasta + '_00_00.BAK'
set @arquivo_DIF = @caminho + 'bkpDIF_' + 'db1' + '_' + @pasta + '_06_01.BAK'

use master
RESTORE DATABASE [db1_teste]
FROM  DISK = @arquivo_FULL
WITH STATS = 5, FILE = 1,  MOVE N'DB1_Novo_Data' TO N'D:\Dados\DB1_Teste.MDF',  MOVE N'DB1_Novo_Log' TO N'L:\Log\DB1_Teste.LDF'
,  NORECOVERY,  NOUNLOAD,  REPLACE
GO

/*  - Restaurando o Diferencial */

use master
RESTORE DATABASE [DB1_Teste]
FROM  DISK = @arquivo_DIF
WITH STATS = 3, FILE = 1,  MOVE N'DB1_Novo_Data' TO N'D:\Dados\DB1_Teste.MDF',
MOVE N'DB1_Novo_Log' TO N'L:\Log\DB1_Teste.LDF',NORECOVERY
GO


RESTORE DATABASE DB1_Teste WITH RECOVERY
GO

If anyone has a good tip thanks

Scope of a variable ends when the batch ends. So, even though you are declaring @arquivo_DIF at the very top, it goes out of scope at the batch separator (GO statement).

,  NORECOVERY,  NOUNLOAD,  REPLACE
GO

/*  - Restaurando o Diferencial */

besides//you need dynamic sql to do this anyway

Why are you restoring the same database twice?

Thanks.
remove the GO statements.
a GO statement ends the previous batch,and destroys the declared variables as well.
if you remove the GO statmeents, the variables will still be there, and you are good to go!
SOLVED.
Thanks for all
