在 MySQL 数据库中搜索全名或名字或姓氏，名字和姓氏在单独的列中

Question

I'm working with an existing database that has first name and last name seperated in the database. I need to create a function that will take one search input and return results. say my database has a structure like....

nameFirst nameLast
Joe       Smith
Joe       Jones
Joe       Brown

How could I, using MySql, take a search input that is say 'Joe Smith' and just get his row? But if I put just 'Joe' in the search field, return them all? Will I need to explode the string with a space? thanks!

Answer 1

SELECT * 
FROM table
WHERE CONCAT( nameFirst,  ' ', nameLast ) LIKE  '%Joe%'  

Be sure to sanitize any user submitted parameters such as "Joe"

Answer 2

SELECT * FROM table WHERE CONCAT(nameFirst, ' ', nameLast) LIKE 'Joe%';

I suggest to use this if you are sure that your search input start with "Joe" to filter more.

In my humble opinion in a lot of cases we don't know if the search input is the name or the surname so I suggest to use this:

SELECT * FROM table WHERE CONCAT(nameFirst,  ' ', nameLast) LIKE  'SEARCH_INPUT%' OR CONCAT(nameLast,  ' ', nameFirst) LIKE 'SEARCH_INPUT%';

Answer 3

$sql = "SELECT * from add_contact  WHERE ( CONCAT(first_name, ' ',last_name)  LIKE '%$search%' OR first_name LIKE '%$search%' OR last_name LIKE '%$search%' OR company LIKE '%$search%') AND (archives='$archives') ORDER BY UNIX_TIMESTAMP(sort_date) DESC";
