错误在SQL查询

我的尝试运行在Visual Studio asp.net的SQL查询，但我收到此错误：错误在SQL查询

You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '' AND JobID = jn.ID GROUP BY JOBID)) as Delivered, ' at line 1

但我无法看到问题的所在。

private static string SearchSQL 
{ 
    get{ 
     return @" set @sql = null; 
      select 
       group_concat(distinct 
        concat(
         'max(case when PieceType = ''', 
         PieceType, 
         ''' then AdvisedQty end) AS ', 
         concat(PieceType) 
        ) 
       )into @sql 
      FROM customer c 
      LEFT JOIN job_address ja ON c.AccountCode = ja.Code AND c.Company_ID = ja.Company_ID 
      JOIN AddressType jat ON ja.AddressType = jat.ID and jat.Description = ''Debtor'' 
      LEFT JOIN job_new jn ON ja.JobID = jn.ID 
      LEFT JOIN job_pieces jp ON ja.JobID = jp.ID 

    WHERE c.Company_ID = ?compid; 

    set @sql = concat('select 
       c.Name, 
       COUNT(distinct jn.ID) as Jobs, 
       SUM((select COUNT(ID) from jobstat where Status = ''DEL'' AND JobID = jn.ID GROUP BY JOBID)) as Delivered, 
       SUM((select COUNT(ID) from jobstat where Status = ''POD'' AND JobID = jn.ID GROUP BY JobID)) as POD, 
       (select COUNT(job_debriefs.ID) from job_debriefs WHERE JobID = jn.JobNo) as Debriefs, 
       sum(jn.OutTurn) as Outturn, 
       SUM(jn.ActualWeight) as GrossWt, 
       SUM(jn.CBM) as CBM, 
       jn.Department, 
       (SELECT Name FROM job_address WHERE AddressType =3 AND JobID = jn.ID) as CollectName, 
       (SELECT Name FROM job_address WHERE AddressType =2 AND JobID = jn.ID) as DeliverName, 
       ', @sql, ' 
      FROM customer c 
      LEFT JOIN job_address ja ON c.AccountCode = ja.Code AND c.Company_ID = ja.Company_ID 
      JOIN AddressType jat ON ja.AddressType = jat.ID and jat.Description = ''Debtor'' 
      LEFT JOIN job_new jn ON ja.JobID = jn.ID 
      LEFT JOIN job_pieces jp ON ja.JobID = jp.ID 

    WHERE c.Company_ID = ?compid 
    GROUP BY c.ID'); 

    prepare stmt from @sql; 
    execute stmt; 
    deallocate prepare stmt; 
          "; 
     } 
    }

好吧，我固定的单引号，但现在的错误上来就是：

You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '?compid GROUP BY c.ID' at line 19

所以那不是问题

如果您尝试直接在DBMS中运行SQL代码，则可能会收到更有用的错误消息。 –

@TheTTGGuy我试着在MySQL Workbench中运行查询，但发生错误：'错误代码：1064.您的SQL语法错误;检查与您的MySQL服务器版本相对应的手册，以便在'max（PieceType ='Carton'然后AdvisedQty结束时的情况）'时使用正确的语法。AS纸箱，最大（在'13号线'时的情况' – user123456789

是有原因的你应该只需要一个（这可能不是问题，但是可以用单个的parens来尝试） – nomistic

你还是一个字符串文字里面是找到compid在这里，所以您需要将单引号加倍，以便在错误消息摘录的DEL值之前将它们转义出来：

SUM((select COUNT(ID) from jobstat where Status = ''DEL'' AND JobID = jn.ID GROUP BY JOBID)) as Delivered, 
SUM((select COUNT(ID) from jobstat where Status = ''POD'' AND JobID = jn.ID GROUP BY JobID)) as POD,

我需要为''Debtor''执行此操作吗？ – user123456789

可能是您的。 –

好的，谢谢。：'near'？compid GROUP BY c.ID'' – user123456789
