原sql:
SELECT a.*,b.* from (SELECT a.id as opener_id,a.name,sum(c.money) as bonus_money,c.year,c.month from sh_opener a LEFT JOIN sh_opener_bonus b on a.id = b.opener_id LEFT JOIN sh_incentive c on b.incentive_id = c.id where a.agent_id = 3 and a.status = 1 and c.year = 2015 and c.month = 11 GROUP BY a.id,c.year,c.month) a LEFT JOIN (SELECT a.id as payment_id,a.opener_id,a.money as payment_money,a.trode_number from sh_opener_bonus_payment a where a.year = 2015 and a.`month` = 11 and a.agent_id = 3) b on a.opener_id = b.opener_id;
这里面有两个子查询语句,其实子查询语句也是表,只不过是存在内存中罢了。
thinkphp实现:
$useYear = date('Y',strtotime('last month')); $this->assign('useYear',$useYear); $useMonth = date('m',strtotime('last month')); $this->assign('useMonth',$useMonth); // 获取上一月人员的奖金金额 // 子查询1 $whereSub1['a.agent_id'] = $this->agent_id; $whereSub1['a.status'] = 1; $whereSub1['c.year'] = $useYear; $whereSub1['c.month'] = $useMonth; $subQuery1 = M()->table('sh_opener a')->join('sh_opener_bonus b on a.id = b.opener_id')->join('sh_incentive c on b.incentive_id = c.id')->where($whereSub1)->group('a.id,c.year,c.month')->field('a.id,a.name,sum(c.money) as bonus_money,c.year,c.month')->select(false); // 子查询2 $whereSub2['a.agent_id'] = $this->agent_id; $whereSub2['a.year'] = $useYear; $whereSub2['a.month'] = $useMonth; $subQuery2 = M()->table('sh_opener_bonus_payment a')->where($whereSub2)->field('a.id as payment_id,a.opener_id,a.money as payment_money,a.trode_number')->select(false); $list = M()->table($subQuery1.' a')->join($subQuery2.' b on a.id = b.opener_id')->select(); $this->assign('list',$list);
