如何选择两行串联的项目就像输入一样

Question

i have mysql table, users: (id, first_name, last_name, ....)

i'd like to do something like this pseudo query

SELECT * FROM users WHERE first_name.' '.last_name = 'john doe' LIMIT 10")

I Want to do this cause i have lots of trouble spliting the string (then i don't know in what order is user typing'

This is my current, not working very good

$phrase = explode(' ',$term);
$last_name = '';
if($phrase[1] != '')
    $last_name= " OR last_name LIKE '%".$phrase[1]."%'";
$qstring = "SELECT usuarios.first_name,usuarios.last_name,
                    usuarios.id as id
            FROM usuarios
            WHERE first_name LIKE '%".$phrase[0]."%' OR last_name LIKE '%".$phrase[0]."%' $last_name LIMIT 5";

Any suggestion to achieve this (by concatenating at query or spliting at php) would be very apreciated

Answer 1

You can concatenate in a MySQL query using CONCAT:

SELECT * FROM users WHERE CONCAT(first_name,' ',last_name) = 'john doe' LIMIT 10

In your code this would become:

SELECT * FROM usuarios WHERE CONCAT(first_name,' ',last_name) LIKE '%{$phrase[0]}%' LIMIT 5
