使用场景：进行某一日期范围内的数据查询

查询结果：空，查询不到符合条件的数据。

Sql展示：

SELECT
	a.dt_plan AS planDate,
	a.sd_status AS planStatus 
FROM
	c_hpl_plan a
WHERE
   a.id_phr = '6576727112f1a21849639530' 

	 -- 第一种写法
	 and a.dt_plan >= DATE_FORMAT('2023-12-01 00:00:00','yyyy-mm-dd HH24:mi:ss')
	 and a.dt_plan <= DATE_FORMAT('2023-12-16 00:00:00','yyyy-mm-dd HH24:mi:ss')
	 
     -- 第二种写法
	 and a.dt_plan BETWEEN DATE_FORMAT('2023-12-01 00:00:00','yyyy-mm-dd HH24:mi:ss') and DATE_FORMAT('2023-12-16 00:00:00','yyyy-mm-dd HH24:mi:ss');
