从表中选择*，其中列包含关键字

My Query SELECT * from users where user_id='$keyword' OR username='$keyword' OR email='$keyword' OR skype='$keyword' OR balance='$keyword' OR spent='$keyword' OR status='$keyword' OR created='$keyword' OR last_auth='$keyword'

Problem

Returning random rows

Use LIKE instead of trying to get the exact value.

SELECT * from  users where user_id LIKE '%$keyword' OR username LIKE '%$keyword%' OR email LIKE '%$keyword%' OR skype LIKE '%$keyword%' OR balance LIKE '%$keyword%' OR spent LIKE '%$keyword%' OR status LIKE '%$keyword%' OR created LIKE '%$keyword%' OR last_auth LIKE '%$keyword%'

If you are using LIKE on a number field use:

CAST(user_id AS CHAR) LIKE '%keyword%'
