Question

我有以下SQL查询：

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;

它会显示如下结果：

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

很好，我可以得到这样的结果，而pound符号已经增加了价值：

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

是否可以使用MySQL查询？

修改过的查询：

         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;

是的，请尝试：

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;
