2. 错误原因
SELECT t.`name`, DATE_FORMAT(STR_TO_DATE('2015'), '%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') 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'
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'
