我需要结合两个表并按两个表日期排序..
医学
| Id | Patientid | Name | Quantity | medicine name | Takingtype | Epoch |
===============================================================================
| 1 | 12 | raja | 20 | Ampicillin | 1-1-1 | 1420446675|
外科
| Id | Patientid | Name | medicine name | Quantity | Epoch |
=======================================================================
| 1 | 12 | raja | Mucinex oral | 10 | 1420446675 |
任何人都可以帮助我吗? 结果应该是这样的,
|s.no| Date | Name | Quantity | medicine name | Takingtype |
=================================================================
| 1 | 1-5-2015 | raja | 20 | Ampicillin | 1-1-1 |
| 2 | 1-5-2015 | raja | 10 |Mucinex oral | |
请帮我加入表格,如上面显示的结果。我正在寻找一个mysql查询..
(我已经在php中更改了纪元时间。)

您是否在MySQL中寻找 UNION ?
SELECT name, quantity, medicine, Takingtype FROM Medicine
UNION ALL
SELECT name, quantity, medicine, NULL FROM Surgical

如果我理解你的问题,那么你想要的不是一个联盟,而是一个联盟。
select * from (
select Name, Quantity, MedicineName, Epoch, Takingtype From Medicine
union all
select Name, Quantity, MedicineName, Epoch, NULL From Surgical
) x order by epoch;
我还假设您希望s.no成为包含行序号的列。据我所知,如果没有临时表,你无法在MySQL中实现这一点(专家可能会在这里纠正我。)
最后,如果您的日期时间确实是时代的一个时间,那么您需要使用FROM_UNIXTIMESTAMP内置函数,
select * from (
select FROM_UNIXTIMESTAMP(Epoch) AS Date, Name, Quantity, MedicineName, Epoch, Takingtype From Medicine
union all
select FROM_UNIXTIMESTAMP(Epoch) AS Date, Name, Quantity, MedicineName, Epoch, NULL From Surgical
) x order by epoch;
