2. 錯誤原因

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內置函數str_to_date的格式是：str_to_date(字符串,日期格式);
在這個查詢SQL中卻是str_to_date(字符串)，導致報錯

3. 解決辦法

修改查詢SQL語句

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'
