如何组合两列并在其中搜索？

Question

我有一张这样的表：

-- users
+----+--------+--------+
| id | f_name | l_name |
+----+--------+--------+
| 1  | Jack   | Smith  |
| 2  | Peter  | Hall   |
| 3  | John   | Price  |
+----+--------+--------+

这是我的疑问：

SELECT u.*,
       match(f_name) against(:input) f_name_order,
       match(l_name) against(:input) l_name_order,
       match(f_name, l_name) against(:input) both_order,
FROM users u
WHERE match(f_name, l_name) against(:input) 
ORDER BY both_order * 4 DESC, l_name_order * 2 DESC, f_name_order DESC
LIMIT 20;

现在我想在输入为john pri时选择表格的最后一行。我当前的查询并不匹配。我怎么能这样做？

你可以使用concat和

select u.*
from users u 
where concat(f_name, ' ', l_name) like concat('%', :input, '%')
