mysql - MySQL - CONCAT 两个字段并在 WHERE 子句中使用它们

Question

正如标题所示，我想知道如何在in 中设置concat两个字段。这是我想要实现的一个例子：where clausemysql

SELECT CONCAT_WS(' ', first_name, last_name) AS name FROM `users`
WHERE name LIKE "%John Doe%"

关键是first_name和last_name是单独的字段，我想让我的PHP应用程序能够搜索完整的人名。

有小费吗？

干杯!

Answer 1

尝试这个 ：：

SELECT CONCAT_WS(' ', first_name, last_name) AS name FROM `users`
WHERE CONCAT_WS(' ', first_name, last_name) LIKE "%John Doe%"

Answer 2

pick up the users as view then query outside select query

select name from (select first_name||last_name FROM `users`
    WHERE frst_name LIKE "%John%" or last name like "%doe%") where name like '%John Doe%'
