在主查詢中使用子查詢

我做喜歡這樣子查詢，但它給錯誤在主查詢中使用子查詢

    SELECT 
       sourceTable3.Total, 
       (sourcetable3.datediff-1) as diff, 
      ADDDATE(ADDDATE(NOW(), INTERVAL FLOOR(diff) MONTH), INTERVAL DAY(NOW()) -   memberToMship_DueDay DAY) As expdate, 
       ExpPayments, 
      MonthlyAmount, 
      SourceTable3.ExpPayments2, 
      FROM 
      (
      SELECT 
       SourceTable2.Total, 
      (SourceTable2.datdiff-1) as diff, 
      SourceTable2.datdiff,     
      ExpPayments, 
      MonthlyAmount, 
      SourceTable2.ExpPayments2, 
      member_Id 
      FROM 
      (
      SELECT 
       SourceTable.Total, 
       ceil(SourceTable.ExpPayments-SourceTable.Total) AS datdiff,     
       SourceTable.ExpPayments, 
       SourceTable.MonthlyAmount, 
      (SourceTable.Total/SourceTable.MonthlyAmount) as ExpPayments2, 
       SourceTable.member_Id 
      FROM 
      ( 
       SELECT       TIMESTAMPDIFF(MONTH,memberToMship_StartDate,memberToMship_EndDate)*  memberToMship_ChargePerPeriod As Total,  
DATEDIFF(GREATEST(NOW(),memberToMship_DueDay),memberToMship_StartDate)/30 AS ExpPayments, 
30* memberToMship_ChargePerPeriod/DATEDIFF(memberToMship_EndDate,memberToMship_StartDate) AS MonthlyAmount, 
member_Id 
      FROM 
      membertomships 
     ) as SourceTable 
    ) as SourceTable2 
) as sourceTable3

但它給錯誤是這樣的...

      Error Code: 1054 
         Unknown column 'sourcetable3.datediff' in 'field list'

會不會有人請幫助。 ..

修改後的代碼：

修改 'e' 和有這樣

012錯誤

錯誤代碼：1054在 '字段列表'

修改後的代碼未知列 'memberTo_Mship_DueDay'：

這是我的表結構

       membership table 
           memberToMship_Id 
          memberToMship_StartDate 
          memberToMship_EndDate 
          memberToMship_DueDay 
          member_Id 

         I want finally these columns expdate , diff , ExpPayments, 
      MonthlyAmount, 





      MODIFIED CODE : 




       SELECT 
      SourceTable3.Total, 

      ADDDATE(ADDDATE(NOW(), INTERVAL FLOOR(diff) MONTH), INTERVAL DAY(NOW()) -   memberToMship_DueDay DAY) As expdate, 
      (Sourcetable3.datdiff-1) as diff, 
     ExpPayments, 
      MonthlyAmount, 
      SourceTable3.ExpPayments2, 
      SourceTable3.member_Id 
      FROM 
      (
       SELECT

和錯誤

     Error Code: 1054

拜託，請檢查您的表 – wonk0

@ wonk0我有一個像這些領域中memberTomship表中的列memberTo_Mship_DueDay ... memberToMship_EndDate，memberToMship_StartDate – user682417

@ user682417你仍然有問題，請給你的桌面截圖與你想要的結果。 – rahularyansharma

錯誤代碼：1054 未知列'差異'在'字段列表'這是我得到的錯誤... – user682417

請參閱上面的編輯... – StevieG

thanq stevie G現在工作... – user682417

我認爲你需要從datediff中刪除e，所以它變成sourcetable3.datdiff。

雅我已經刪除，但它給這樣的錯誤...錯誤代碼：1054。'字段列表'中的未知列'memberToMship_DueDay' – user682417

@ user682417：我會檢查您所指的實際表格的列拼寫。 –

問題就在這裏sourceTable3.Total，（sourcetable3.datdiff-1）as diff， ADDDATE（ADDDATE（NOW（），INTERVAL FLOOR（diff）MONTH），INTERVAL DAY（NOW（）） - memberToMship_DueDay DAY），memberToMship_DueDay不在字段列表 – user682417

使用了不同的情況下，爲SourceTable3：

sourceTable3.Total,
(sourcetable3.datediff-1) as diff,
SourceTable3.ExpPayments2,
) as sourceTable3

如果你是在Linux上，嘗試所有更改爲SourceTable3。請參閱Identifier Case Sensitivity。

看起來你有行一個錯字，其中該列中標識：

ceil(SourceTable.ExpPayments-SourceTable.Total) AS datdiff, 
              -----------^^-----

但是，你應該附上datediff在反引號，因爲它是一個保留MySQL的關鍵字。

ceil(SourceTable.ExpPayments-SourceTable.Total) AS `datediff`,

多數民衆贊成在罰款..但現在我得到了這樣的不同錯誤...錯誤代碼：1054 未知列'memberToMship_DueDay'在'字段列表' – user682417

那麼，這個錯誤信息的哪一部分給你帶來麻煩？是根本不存在的sourcetable3命名DATEDIFF列，它是datdiff

錯誤代碼：1054未知列'memberTo_Mship_DueDay 'in'字段列表這是錯誤 – user682417

@ user682417檢查針對實際表格的拼寫。同時檢查你是否使用相同的情況。如果你在linux上，列名和表名是區分大小寫的。 –

我不使用linux ..我使用c＃php和mysql ... – user682417
