mysql - 根据周和年选择数据

Question

我有这个sql:

SELECT YEAR(`end`) as week, WEEK(`end`) as year
FROM table
WHERE week=24 AND year=2016 

但是我收到错误where 子句中的未知列周。我做错了什么？请帮帮我。提前谢谢

Answer 1

您不能在 where 子句中使用别名，试试这个；)

SELECT WEEK(`end`) as week, YEAR(`end`) as year
FROM table
WHERE WEEK(`end`)=24 AND YEAR(`end`)=2016
