要求如下显示：

此处用到了行转列，由于列不固定，考虑使用动态sql

SET @d=(select GROUP_CONCAT('if(sdkname=\'',sdkname,'\' ,total_count,0) as `',sdkname,'`') FROM (SELECT DISTINCT sdkname FROM pcik_log_dep.u1ge_query_log ) A); SET @sql=CONCAT('select date,',@d,'from pcik_log_dep.u1ge_query_log group by date');  PREPARE sdtmt from @sql;EXECUTE sdtmt;deallocate prepare sdtmt;
