### 需求描述：项目中首页用几个图表来展示销售数据，根据不同的时间范围、时间维度来查询，有些时间段没有数据的，图表中各项数据显示为0。 ``` /** * * 终端报表 * User: wenhu8000 */ function getReport() { #--获取公共参数 $d = $this->getCommonData();#halt($d); #--查询条件 /*$where['RD.i_code'] = ['>', -1];*/ #--排序 $order = "total DESC"; #--时间范围 if (!empty($d['range'])) { $time = $this->getTimeRange($d['range']); $d['staTime'] = $time['staTime']; $d['endTime'] = $time['endTime']; $order = "times"; } #--时间维度 if (!empty($d['times'])) { $times = $this->getTimes($d['times']); $order = "times"; } else { $times = "%Y-%m"; $d['times'] = "month"; } #--计算出起始时间按不同时间维度的差，最小为 1 $limit = Db::query("SELECT TIMESTAMPDIFF(".$d['times'].",?,?) as num from table1 limit 1",[$d['staTime'],$d['endTime']])[0]['num']?:1;#halt($limit); #--查询数据 $sql = Db::table("(SELECT DATE_FORMAT(@date := DATE_ADD(@date, INTERVAL + 1 " . $d['times'] .
