mysql查询在同一个表上执行多个内部联接

Question

我需要在同一个表上执行多个连接。以下是我的查询。 当我执行以下查询时，它为我提供了单个列的重复记录。 谁能告诉我哪里出错？

$result=mysql_query("SELECT DISTINCT *,CONCAT(phno, ' ', vnumber) AS source,CONCAT(phno, ' ', vnumber) AS destination FROM gcm_users as gu
                                                INNER JOIN message_Log as ml1 ON gu.imei= ml1.Source_ID 
                                                INNER JOIN message_Log as ml2 ON gu.imei= ml2.Destination_ID
                                                WHERE  gu.id={$_SESSION['uid']}");
