私は次のSQLクエリを持っているMySQLの

Question

に通貨記号を追加しようとすると：

  mshiptype_name  mshipsold  value 
      --------------  ---------  ----- 
      gold     3    3800.00 
      silver    4    4800.00 

その罰金は、私がこのような結果を得ることができます。

SELECT mshipType_Name, 
     COUNT('x') AS mshipssold, 
     sum(memberToMship_InductionFee+memberToMship_JoinFee+ 
      (IF(mshipOption_Period='year', 
      TIMESTAMPDIFF (YEAR ,memberToMship_StartDate, memberToMship_EndDate), 
      TIMESTAMPDIFF (MONTH ,memberToMship_StartDate, memberToMship_EndDate)) * memberToMship_ChargePerPeriod)) as value 
FROM membertomships 
    INNER JOIN mshipoptions on membertomships.mshipOption_Id = mshipoptions.mshipOption_Id 
    INNER JOIN mshiptypes on mshipoptions.mshipType_Id = mshiptypes.mshipType_Id 
WHERE memberToMship_StartDate BETWEEN '2011-06-26' AND '2011-07-26' 
GROUP BY mshipType_Name; 

それは、このような結果が表示されますポンド記号は値で追加されました：

  mshiptype_name  mshipsold  value 
      --------------  ---------  ----- 
      gold     3    £ 3800.00 
      silver    4    £ 4800.00 

MySQLクエリで可能ですか？

変形QUERY：

  SELECT set names utf-8,mshipType_Name, COUNT('x') AS mshipssold, 
           CONCAT('£', sum(memberToMship_InductionFee+memberToMship_JoinFee+ 
            (IF(mshipOption_Period='year', 
            TIMESTAMPDIFF (YEAR ,memberToMship_StartDate, memberToMship_EndDate), 
            TIMESTAMPDIFF (MONTH ,memberToMship_StartDate, memberToMship_EndDate)) * memberToMship_ChargePerPeriod))) as value 
           FROM membertomships 
           inner join mshipoptions on membertomships.mshipOption_Id = mshipoptions.mshipOption_Id 
           inner join mshiptypes on mshipoptions.mshipType_Id = mshiptypes.mshipType_Id 
           WHERE memberToMship_StartDate BETWEEN '2011-06-26' AND '2011-07-26' 
           GROUP BY mshipType_Name;

はい、してみてください：

set names utf8; 
SELECT mshipType_Name, COUNT('x') AS mshipssold, 
           sum(memberToMship_InductionFee+memberToMship_JoinFee+ 
            (IF(mshipOption_Period='year', 
            TIMESTAMPDIFF (YEAR ,memberToMship_StartDate, memberToMship_EndDate), 
            CONCAT('£ ', TIMESTAMPDIFF (MONTH ,memberToMship_StartDate, memberToMship_EndDate)) * memberToMship_ChargePerPeriod))) as value 
           FROM membertomships 
           inner join mshipoptions on membertomships.mshipOption_Id = mshipoptions.mshipOption_Id 
           inner join mshiptypes on mshipoptions.mshipType_Id = mshiptypes.mshipType_Id 
           WHERE memberToMship_StartDate BETWEEN '2011-06-26' AND '2011-07-26' 
           GROUP BY mshipType_Name;
