语法错误帮助

Question

我有这个脚本可以正常工作，但是当我更改目录路径时，它似乎收到此语法错误“字符串后未关闭的引号”会导致这种情况的问题。

DECLARE @db VARCHAR(50), 
@sql NVARCHAR(400),
@country varchar(100)
DECLARE barcardi cursor for 
select [ProjectDB] from [DBA].[dbo].[BacardiExport] order by [Country] asc
open barcardi 
fetch next from barcardi into @db
while @@FETCH_STATUS = 0
    begin
        set @country = (select country from [DBA].[dbo].[BacardiExport] where [ProjectDB] = @db)
        set @sql = 'BACKUP DATABASE ['+@db+'] TO  DISK = N''D:\ConfirmitN02BackupNew\BacardiProjectBackup\Bacardi_'+@country+'_'+@db+'.bak'' WITH NOFORMAT, NOINIT, SKIP, NOREWIND, NOUNLOAD,  STATS = 10'
        exec sp_executesql @sql
        --print @sql

        set @country = (select country from [DBA].[dbo].[BacardiExport] where [ProjectDB] = @db)
        set @sql = 'RESTORE DATABASE [Bacardi_'+@country+'_'+@db+'] FROM  DISK = N''D:\ConfirmitN02BackupNew\BacardiProjectBackup\Bacardi_'+@country+'_'+@db+'.bak'' WITH  FILE = 1,  MOVE N'''+@db+'_dat'' TO N''D:\ConfirmitN02-MDF\confirmit_sql_data\Bacardi_'+@country+'_'+@db+'.mdf'',  MOVE N'''+@db+'_log'' TO N''D:\ConfirmitN02-LDF\confirmit_sql_log\Bacardi_'+@country+'_'+@db+'.ldf'',  NOUNLOAD,  REPLACE,  STATS = 5'
        exec sp_executesql @sql
        --print @sql

        set @country = (select country from [DBA].[dbo].[BacardiExport] where [ProjectDB] = @db)
        set @sql = 'UPDATE [DBA].[dbo].[BacardiExport] set [CopyProjectDB] =  ''Bacardi_'+@country+'_'+@db+''' where [ProjectDB] = '''+ @db +''''
        exec sp_executesql @sql
        --print @sql

        update [DBA].[dbo].[BacardiExport] set [Copied] = 1 where [ProjectDB] = @db
        update [DBA].[dbo].[BacardiExport] set [ProcessDate] = getdate() where [ProjectDB] = @db

    fetch next from barcardi into @db
    end
close barcardi
deallocate barcardi

这是输出的一部分。

很高兴您解决了截断问题，但我可以提供一个不会出现这种情况的替代方案，消除对光标脚手架等的需求吗？

DECLARE @src nvarchar(max) = N'', @sql nvarchar(max) = N'';

SELECT @src = N'
  BACKUP DATABASE $qdb$ TO  DISK 
  = N''D:\ConfirmitN02BackupNew\BacardiProjectBackup\Bacardi_$c$_$db$.bak''
   WITH NOFORMAT, NOINIT, SKIP, NOREWIND, NOUNLOAD,  STATS = 10;

  RESTORE DATABASE [Bacardi_$c$_$db$] FROM DISK 
  = N''D:\ConfirmitN02BackupNew\BacardiProjectBackup\Bacardi_$c$_$db$.bak'' 
   WITH  FILE = 1,  MOVE N''$db$_dat'' 
   TO N''D:\ConfirmitN02-MDF\confirmit_sql_data\Bacardi_$c$_$db$.mdf'',
   MOVE N''$db$_log'' TO N''D:\ConfirmitN02-LDF\confirmit_sql_log\Bacardi_$c$_$db$.ldf'',
   NOUNLOAD,  REPLACE,  STATS = 5;

  UPDATE [DBA].[dbo].[BacardiExport] set [CopyProjectDB] = ''Bacardi_$c$_$db$'',
    Copied = 1, ProcessDate = GETDATE() where [ProjectDB] = ''$db$'';';

SELECT @sql += REPLACE(REPLACE(REPLACE(@src,   
  N'$c$',country),N'$db$',ProjectDB),N'$qdb$',QUOTENAME(ProjectDB))
FROM DBA.dbo.BacardiExport;

PRINT @sql; -- this may not display everything, depending on how many rows
-- EXEC sys.sp_executesql @sql;
