Question

我写了一些SQL从备份文件还原数据库-运行它时，出现两个错误：

105消息，第15级，状态1，第5行
  字符串'D：\ MSSQL \ MSSQL13'后面的引号引起来。

第15级状态1行5的消息102
  'D：\ MSSQL \ MSSQL13'附近的语法不正确。

我的SQL：

DECLARE @sql VARCHAR(256)
DECLARE @name VARCHAR(50) -- database name  
DECLARE @path VARCHAR(256) -- path for backup files  
DECLARE @dataPath VARCHAR(256) --path for data files
DECLARE @backupFile VARCHAR(256) -- filename for backup  
DECLARE @restoreDBName sysname -- name of db to be restored
DECLARE @MDFLogicalName VARCHAR(256)
DECLARE @LDFLogicalName VARCHAR(256)
DECLARE @MDFPhysicalName VARCHAR(256)
DECLARE @LDFPhysicalName VARCHAR(256)

-- specify database backup directory
SET @path = 'D:\MSSQL\MSSQL13.MSSQLSERVER\MSSQL\Backup\' 

--specify path for data files
SET @dataPath = 'D:\MSSQL\MSSQL13.MSSQLSERVER\MSSQL\DATA\'

SET @restoreDBName ='eLot_Test'
SET @MDFLogicalName = 'eLot_Startup'
SET @LDFLogicalName = 'eLot_Startup_log'

SET @MDFPhysicalName = 'eLot_Testuction.mdf'
SET @LDFPhysicalName = 'eLot_Testuction_1.ldf'

-- specify filename format
SELECT @fileDate = CONVERT(VARCHAR(20), GETDATE(), 112) 

DECLARE db_cursor CURSOR READ_ONLY FOR  
    SELECT name 
    FROM master.dbo.sysdatabases 
    WHERE name IN ('eLot_prod', 'eLot_Test')  -- include these databases

OPEN db_cursor   

FETCH NEXT FROM db_cursor INTO @name   

WHILE @@FETCH_STATUS = 0   
BEGIN   
    SET @backupFile = @path + @name + '_' + @fileDate + '.BAK'  

    BACKUP DATABASE @name TO DISK = @backupFile  

    FETCH NEXT FROM db_cursor INTO @name   
END   

CLOSE db_cursor   
DEALLOCATE db_cursor  

SET @sql = 'RESTORE DATABASE [' + @restoreDBName + '] FROM DISK = ''' + @backupFile +'''
            WITH MOVE ''' + @MDFLogicalName + ''' TO ''' + @dataPath + @MDFPhysicalName +''',
            MOVE ''' + @LDFLogicalName + ''' TO ''' + @dataPath + @LDFPhysicalName +''' '
 EXEC (@sql)

当我使用PRINT @cmd打印出用于RESTORE的SQL时，它可以正常打印，并且可以在查询窗口中运行它：

RESTORE DATABASE [eLot_Test] 
FROM DISK = 'D:\MSSQL\MSSQL13.MSSQLSERVER\MSSQL\Backup\eLot_Test_20180801.BAK'
WITH MOVE 'eLot_Startup' TO 'D:\MSSQL\MSSQL13.MSSQLSERVER\MSSQL\DATA\eLot_Testuction.mdf' ,
     MOVE 'eVIPs_Startup_log' TO 'D:\MSSQL\MSSQL13.MSSQLSERVER\MSSQL\DATA\eLot_Testuction_1.ldf'

但是，当我尝试在脚本中执行它时，出现了以上两个错误。

任何帮助将不胜感激。谢谢
