直接上sql语句:

select * from orderinfo_view;

SET @EE='';
set @str_tmp='';
SELECT @EE:=CONCAT(@EE,'(IF(ColumnEnglishName=\'',ColumnEnglishName,'\'',',ColumValue,ColumValue)) AS ',ColumnEnglishName,',')
 as aa into @str_tmp FROM (SELECT DISTINCT ColumnEnglishName FROM orderinfo_view) A order by length(aa) desc limit 1; 
SET @QQ=CONCAT('SELECT custmerID,PlatformAccount,AddTime,Inspection_categoryID,serviceCost,ServiceName,ordercodeID,  ',
LEFT(@str_tmp,char_length(@str_tmp)-1),' FROM orderinfo_view GROUP BY ordercodeID');
PREPARE stmt  FROM @QQ; 
EXECUTE stmt ; 

效果不统一,值不对应了,求解
