Php 列出唯一的行，同时根据给定日期连接两个表

我有两个表，一个包含预订信息，另一个包含集装箱产品信息。下订单时，在预订表中创建一条新记录。我希望得到一个组合表，其中包含基于给定日期的两个表中的所有列

表：预订

------------------------------------------ | booth_number| booking_date | status | |------------------------------------------| | 1 | 2014-08-15 | booked | | 2 | 2014-09-10 | booked | | 3 | 2014-09-11 | booked | ------------------------------------------ ------------------------------------------ |展位号|预订日期|状态| |------------------------------------------| |1 | 2014-08-15 |预订| |2 | 2014-09-10 |预订| |3 | 2014-09-11 |预订| ------------------------------------------ 表：产品

----------------------------------------------------------------------------- | booth_number| desc | locked | type | request_date | status | |------------------------------------------|--------|--------------|----------| | 1 | 2 x bottles | true | booth | 2014-08-15 | booked | | 2 | 2 x bottles | | booth | | | | 3 | 4 x bottles | | booth | | | | 4 | 4 x bottles | | booth | | | | 5 | 5 x bottles | | booth | | | | 6 | 5 x bottles | | booth | | | ----------------------------------------------------------------------------- ----------------------------------------------------------------------------- |展位号|描述|锁定|类型|请求|日期|状态| |------------------------------------------|--------|--------------|----------| |1 | 2瓶|真实|展位| 2014-08-15 |预订| |2 | 2瓶| |展位| |124;| |3 | 4瓶| |展位| |124;| |4 | 4瓶| |展位| |124;| |5 | 5瓶| |展位| |124;| |6 | 5瓶| |展位| |124;| -----------------------------------------------------------------------------
