錯誤在SQL查詢

我的嘗試運行在Visual Studio asp.net的SQL查詢，但我收到此錯誤：錯誤在SQL查詢

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

但我無法看到問題的所在。

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，我固定的單引號，但現在的錯誤上來就是：

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

所以那不是問題

如果您嘗試直接在DBMS中運行SQL代碼，則可能會收到更有用的錯誤消息。 –

@TheTTGGuy我試着在MySQL Workbench中運行查詢，但發生錯誤：'錯誤代碼：1064.您的SQL語法錯誤;檢查與您的MySQL服務器版本相對應的手冊，以便在'max（PieceType ='Carton'然後AdvisedQty結束時的情況）'時使用正確的語法。AS紙箱，最大（在'13號線'時的情況' – user123456789

是有原因的你應該只需要一個（這可能不是問題，但是可以用單個的parens來嘗試） – nomistic

你還是一個字符串文字裏面是找到compid在這裏，所以您需要將單引號加倍，以便在錯誤消息摘錄的DEL值之前將它們轉義出來：

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,

我需要爲''Debtor''執行此操作嗎？ – user123456789

可能是您的。 –

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