メインクエリでサブクエリを使用して

Question

私はこのようなサブクエリのように行っているが、それは誤りに

    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 

を与えていたが、それはこのようなエラーを与えていた...

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

は、いずれかのPLSのに役立つだろう。 ..

変更したコード：

修正 'E' と、この

012のようなエラーが発生しました

エラーコード：1054 'フィールドリスト'

変更されたコードで 不明な列 'memberTo_Mship_DueDay'：

は、これが私のテーブル構造

       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 
      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 

とエラーになり

     Error Code: 1054 
         Unknown column 'memberToMship_DueDay' in 'field list' 

いずれかのplsが助けるでしょう...

SELECT 
     SourceTable2.Total, 
     ADDDATE(ADDDATE(NOW(), INTERVAL FLOOR(diff) MONTH), INTERVAL DAY(NOW()) -memberToMship_DueDay DAY) As expdate, 
     datdiff, 
     diff, 
     SourceTable2.ExpPayments, 
     SourceTable2.MonthlyAmount, 
     (SourceTable2.Total/SourceTable2.MonthlyAmount) as ExpPayments2, 
     SourceTable2.expdate, 
     SourceTable2.member_Id 
FROM 
( 
    SELECT 
     memberToMship_DueDay, 
     SourceTable.Total, 
     SourceTable.expdate 
     ceil(SourceTable.ExpPayments-SourceTable.Total) AS datdiff, 
     ceil(SourceTable.ExpPayments-SourceTable.Total) -1 As diff, 
     SourceTable.ExpPayments, 
     SourceTable.MonthlyAmount, 
     (SourceTable.Total/SourceTable.MonthlyAmount) as ExpPayments2, 
     SourceTable.expdate, 
     SourceTable.member_Id 
    FROM 
    ( 
     SELECT 
      memberToMship_DueDay, 
      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 

Answer 2

datediffからeを削除する必要があると思いますので、sourcetable3.datdiffになります。

Answer 3

あなたはSourceTable3のために異なるケースを使用しています

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

あなたがLinux上である場合は、SourceTable3にそれらのすべてを変更してみてください。 Identifier Case Sensitivityを参照してください。

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

しかし、それは予約MySQLのキーワードであるので、あなたがバッククォートでdatediffを囲む必要があります：あなたは、その列が特定されたラインのタイプミスを持っているよう

Answer 4

が見えます。

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

Answer 5

このエラーメッセージのどの部分に問題がありますか？ sourcetable3にDATEDIFFという名前の列が単にありません、それはdatdiff
