从PHP和MYSQL中的名字或姓氏的首字母搜索

Question

I need to search first name or last name from the beginning of characters. For example, firstname is Michael and lastname is Jordan. If I search "dan" or "hae" words, it shouldn't return result. Only if I search "mic" or "jor", it should return firstname and lastname together. Is there any way to do it with mysql ?

My following code does not return what I expect.

select * from users where (firstname like '%$searchWord%' or lastname like '%$searchWord%')

Answer 1

如果只想从单词的开头搜索，则只需将通配符放在条件的末尾：

SELECT * FROM `users` WHERE (`firstname` LIKE '$searchWord%' OR `lastname` LIKE '$searchWord%')

Answer 2

Remove the first % in your query for each term.

select * from users where (firstname like '$searchWord%' or lastname like '$searchWord%')

This will search for the first letters exactly with anything that matches following.
