MySql中按周、月统计数量

经需求要求对某个表进行按每周、每月统计报表显示，以下为sql

1、按周统计数据:

SELECT
    DATE_FORMAT( CreateDate, '%Y-%u' ) AS WEEK,
    DATE_FORMAT(date_sub( CreateDate, INTERVAL dayofweek( CreateDate )- 2 DAY ),'%Y-%m-%d') AS CreateDate,
    count(*) AS count 
FROM
    gyl_order 
GROUP BY
    WEEK;

2、按月统计数据:

    SELECT
    DATE_FORMAT( CreateDate, '%Y-%m' ) AS Month,
    DATE_FORMAT( CreateDate, '%Y-%m-01' ) AS CreateDate,
    count(*) AS count 
FROM
    gyl_order 
GROUP BY
