MySQL内置函数str_to_date的格式是:str_to_date(字符串,日期格式);
在这个查询SQL中却是str_to_date(字符串),导致报错
3. 解决办法
修改查询SQL语句
SELECT
t.`name`,
DATE_FORMAT(STR_TO_DATE(‘2015‘,‘%Y‘), ‘%Y‘) AS statisDate,
ROUND(IFNULL(SUM(t.`amount`), 0), 3) AS amount
FROM
t_stu_info t
WHERE 1 = 1
AND DATE_FORMAT(t.statisDate, ‘%Y‘) = ‘2015‘
UNION
ALL
SELECT
t.`name`,
DATE_FORMAT(STR_TO_DATE(‘2014‘,‘%Y‘), ‘%Y‘) AS statisDate,
ROUND(IFNULL(SUM(t.`amount`), 0), 3) AS amount
FROM
t_stu_info t
WHERE 1 = 1
AND DATE_FORMAT(t.statisDate, ‘%Y‘) = ‘2014‘
