MySQL使用第二个表中的max和其他参数左键连接两个表

拥有这些表并需要将它们连接起来以创建最终列表

想要这些结果吗 -在本例中，显示一个用户的帐户表。 -显示附加到帐户的最后一个日志。如果不存在，则仍显示/NULL -仅拉取“跟进”日志类型的日志。\u type=2 -首先按最旧的附加日志对列表进行排序。日志日期asc

---------------------------------------------------------------------------
| COMPANY    | TYPE            |  USER     | DATE          | NOTE         |
---------------------------------------------------------------------------
| audi       | follow up       |  bob      | 2014-01-01    | Hello        |
---------------------------------------------------------------------------
| bmw        | follow up       |  bob      | 2014-06-03    | ABC          |
---------------------------------------------------------------------------
| mercedes   | NULL            |  bob      | NULL          | NULL         |
---------------------------------------------------------------------------

当前代码如下所示

select c.COMPANY, lt.TYPE, u.NAME, l.DATE, l.NOTE from accounts c 
  LEFT JOIN users u ON c.ACCOUNT_OWNER = u.USER_ID 
  LEFT JOIN logs l ON ( (c.ID_COMPANY = l.COMPANY) && l.TYPE = '2' && u.USER_ID = 100
  LEFT JOIN log_type lt ON l.TYPE = lt.TYPE_ID 
  WHERE u.USER_ID = 100 && l.TYPE = '2' 
  GROUP BY c.COMPANY_ID
  ORDER BY l.DATE asc

苏..什么不起作用？得到这个结果的唯一方法是一个带有硬编码“bob”或硬编码“mercedes”的联盟。
