很久沒用tp了，覺得tp 用久了，都不知道php為何物。來到了公司又用起了tp2.1，行，沒問題，哥之前用過3.1.
問題來了，做的是日考勤和月考勤統計，我汗，tp的關聯查詢，統計查詢，是搞不定了，能搞的話，效率也是不過關，大哥說的，我還體會不到。
參考大哥的sql改吧：
alter table `tbl_attendance` add column `check_unnormal` int null default 1 after `geo_normal`;
alter table `tbl_attendance` drop column `real_name`;
select usr_cal.user_id,usr_cal.real_name,
ifnull(sum(checkintbl.nolate),0) as checkin_late_sum,
ifnull (sum(checkintbl.geo_normal),0) as checkin_geo_unnormal_sum,
ifnull (sum(checkouttbl.nolate),0) as checkout_late_sum,
ifnull (sum(checkouttbl.geo_normal),0) as checkout_geo_unnormal_sum,
ifnull (sum(checkintbl.check_unnormal),0) as checkin_check_sum,
ifnull (sum(checkouttbl.check_unnormal),0) as checkout_check_sum,
ifnull (sum(coalesce(checkintbl.nocheck,1)),0) as checkin_nocheck_sum,
ifnull (sum(coalesce(checkouttbl.nocheck,1)),0) as checkout_nocheck_sum

不管是2.1還是3.1都是這麼說的，我怎麼嘗試怎麼不行，怎麼查怎麼不行，$model = m();網上的解決方案，也不行，問梁哥，說隨便例項化乙個物件就行了，各種嘗試
$tag = m('tag');
$tag = new model('tag');
$tag->query('select * from tbl_tag');這麼簡單的都不行，我徹底無語，崩潰了，
貼上了$group = d('group');$group->query($sql); 結果出來了，就這麼出來了，怎麼就這麼不靈活呢，就不知道m和d換著試試，
怎麼就這麼不靈活呢，自己在一遍一遍的告訴自己
