sqlit中使用到的查询语句

+ "(select sum(price) as mysum,consumetype.title as tt,consumetype.parentid as pid from mybill "
+ "left join consumetype on mybill.typeid =consumetype.id "
+ "group by mybill.typeid) as tb group by tb.pid order by sum(mysum) desc";

4.这个是有个分类表，有个账单表，根据分类中的子分类分类统计再排序：

select sum(price),consumetype.title from mybill "
+ "left join consumetype on mybill.typeid =consumetype.id "
+ "group by mybill.typeid order by sum(price) desc";

5.根据时间来比较选择：

 select * from MyBill where createTime < datetime(‘2015-05-19‘)

相应的其他时间函数方式如下：

        *     select datetime(‘now‘); 
*     select datetime(‘2006-10-17 00:20:00‘,‘+1 hour‘,‘-12 minute‘);
* select date(‘2006-10-17‘,‘+1 day‘,‘+1 year‘);
* select datetime(‘now‘,‘start of year‘);
* select datetime(‘now‘,‘start of month‘);
* select datetime(‘now‘,‘start of day‘);
* select datetime(‘now‘,‘+10 hour‘,‘start of day‘,‘+10 hour‘);
* select datetime(‘now‘,‘localtime‘);
* select datetime(‘now‘,‘+8 hour‘);
