php - MySQL链多个 "Match Against"

Question

我无法让这段代码工作。知道如何改变吗？我尝试在整个条件周围添加 ( ) 但这似乎也无法解决问题。

 SELECT * FROM clients WHERE 
        MATCH(LNAME) AGAINST('aaaa') OR
        MATCH(FNAME) AGAINST('aaaa') OR
        MATCH(MAIL) AGAINST('aaaa') OR
        MATCH(TEL) AGAINST('aaaa')

Answer 1

 SELECT * FROM `clients` WHERE 
        MATCH(`LNAME`) AGAINST('aaaa') OR
        MATCH(`FNAME`) AGAINST('aaaa') OR
        MATCH(`MAIL`) AGAINST('aaaa') OR
        MATCH(`TEL`) AGAINST('aaaa')

或

SELECT * FROM `clients` WHERE MATCH(`LNAME`,`FNAME`,`MAIL`,`TEL`) AGAINST('aaaa');
