Php MySQL查询选择数据

尝试查询4小时。例如，我有这样的数据：

did   title      number_link    ltitle
35  about.html        1          NULL    <- this
35  about.html        2          NULL    <- this
36  about.html        1          NULL
35  contact.php       1          NULL    <- this  
35  contact.php       3          NULL    <- this  
36  contact.php       1          NULL  

did标题编号\u链接
35 about.html 1 NULL此查询将允许您获取行中的所有列，而不仅仅是
标题
和
数字链接

SELECT  a.*
FROM    tableName a
        INNER JOIN
        (
            SELECT  title, number_link, MIN(did) did
            FROM    tableName
            GROUP   BY title, number_link
        ) b ON a.title = b.title AND
                a.number_link = b.number_link AND
                a.did = b.did

按标题、编号链接从表组中选择标题、编号链接
 你能告诉我们你在4小时内试过什么吗？
SELECT  a.*
FROM    tableName a
        INNER JOIN
        (
            SELECT  title, number_link, MIN(did) did
            FROM    tableName
            GROUP   BY title, number_link
        ) b ON a.title = b.title AND
                a.number_link = b.number_link AND
                a.did = b.did

SELECT *
FROM table_name
GROUP BY title, number_link
