Mysql join query on three tables with multiple columns

Question

I have three tables like this:

Specialisation

sid | s_name
--------------
 1  | test 1
 2  | test 2  

Person

pid | name | sid
------------------
 1  | ABC  |  1
 2  | XYZ  |  2

Timing

tid | time_from | time_to  | pid
----------------------------------
 1  | 08:00:00  | 10:00:00 |  1
 2  | 20:00:00  | 22:00:00 |  1
 3  | 09:00:00  | 14:00:00 |  2
 4  | 19:00:00  | 20:00:00 |  2

**I want to get result something like this*

pid | name | s_name | time_from  | time_to
--------------------------------------------
 1  | ABC  | test 1 | 08:00:00   | 10:00:00

Description:
All three tables are connected.
I want all records where
specialisation id = '1'
person name Like 'ABC'
timing is in between '08:00:00' and '10:00:00'.

I tried several combinations of mysql joins but not able to fetch the data correctly.

Answer 1

You can use INNER JOIN for this,

SELECT  a.pid, a.name,
        b.sname,
        c.time_from,
        c.time_to
FROM    person a
        INNER JOIN specialisation b
            ON a.sid = b.sid
        INNER JOIN Timing c
            ON a.pid = c.pid
WHERE   a.sid = 1 and 
        a.name='ABC'  AND 
        c.time_from >= '08:00:00' AND c.time_to <= '10:00:00'

Answer 2

You can use Simple Join like this

     Select P.pid , name , s_name ,time_from ,
     time_to from Specialisation S 
     Join Person P on P.sid=S.sid 
     Join Timing T on T.pid= P.pid 
     where T.time_from >= '08:00:00' AND T.time_to <='10:00:00' And P.name='ABC';
