数据补全 小时 近七天 ${unionSql} 不加order by自动按 order by的字段升序排列

这里小时补全数据是list<String>时间大于2 补全中间间隔的时间,而近七日的补全是讲七日的返回,不会返回null

group by 字段 不加order by自动按 order by的字段升序排列 最好是加上order by date

sql注意之 去掉09:00前面的0  select (CASE WHEN LEFT(aa.date, 1)='0' TH
EN RIGHT(aa.date, 4) ELSE aa.date end) as date

//这里使用%k如果补齐成09:00不带前面的0,则group by order by date排序就会出现问题,9:00会在10:00的后面
-- 如果库里没有,都可以用这个方法进行补全 因为后面是用了group by日期  就近展示前面的数据,比如前面有9点的数据,就不用后面UNION (SELECT '09:00', 0)的9点的0数据了,所以就不用 SUM(aa.customerPersonTimes)了,  妥了！至于sql中间那一长串的UNION语句，那就根据选择的日期用java生成吧
