I need to combine two tables and order by the two tables date..
Medicine
| Id | Patientid | Name | Quantity | medicine name | Takingtype | Epoch |
===============================================================================
| 1 | 12 | raja | 20 | Ampicillin | 1-1-1 | 1420446675|
Surgical
| Id | Patientid | Name | medicine name | Quantity | Epoch |
=======================================================================
| 1 | 12 | raja | Mucinex oral | 10 | 1420446675 |
Can any one help me? The Result should be like this,
|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 | |
Please help me join the tables like the result showed above. I'm looking for a mysql query..
(I have changed the epoch time in to date in php..)
Are you looking for UNION in MySQL?
SELECT name, quantity, medicine, Takingtype FROM Medicine
UNION ALL
SELECT name, quantity, medicine, NULL FROM Surgical
If I understand your question right, then what you want is not a join, it's a union.
select * from (
select Name, Quantity, MedicineName, Epoch, Takingtype From Medicine
union all
select Name, Quantity, MedicineName, Epoch, NULL From Surgical
) x order by epoch;
I also assume that you want s.no to be a column that contains row ordinals. To my best knowledge you cannot really achieve that in MySQL without a temporary table (experts might correct me here).
Finally, if your datetime is indeed a time from the epoch, you need to use a FROM_UNIXTIMESTAMP builtin, something along the lines of
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;
