Mysql three table join results empty set


Hello I have three tables that I have joined but it returns empty result even though there suppose to some result. Here is my sql

SELECT c.code,c.name, a.ltp as begning, b.ltp as enddate, d.interim_cash,d.interim_rec_date,
CAST(((b.ltp - a.ltp) / a.ltp * 100) AS DECIMAL(10, 2)) as chng
FROM eod_stock a
JOIN eod_stock b ON a.company_id = b.company_id
LEFT OUTER JOIN company AS c
ON c.ID = a.company_id
RIGHT JOIN divident_info AS d
ON c.ID = d.company_id
WHERE a.entry_date = "2012-09-24"
AND b.entry_date = "2012-09-25"
AND d.interim_rec_date BETWEEN "2012-09-24" AND "2012-09-25"
AND a.company_id IN (13, 2)
AND d.company_id IN (13,2);

The result i am expecting is like this:

+--------+-----------------+---------+--------+--------+------------------+------------+
| code   | name            | begning | end    | chng   | interim_rec_date |interim_cash|
+--------+-----------------+---------+--------+--------+------------------+------------+
| ABBANK | AB BANK LIMITED |  518.00 | 459.00 | -11.39 |2012-09-24        |10          |
| 1STICB | 1ST ICB M.F.    |  227.00 | 253.00 |  11.45 |                  |            |
+--------+-----------------+---------+--------+--------+------------------+------------+

But I am getting empty set in my result is this because the second one interim info is 0? how can I get all info like above if row is empty then it could be blank but i need other info related to it.

Here are my table schema:

eod_stock:

Please can you help me to find out the result?


Solution

  • So finally I got what i needed here is the query:

     SELECT c.code,c.name, a.ltp as begning, b.ltp as enddate, d.interim_cash,d.interim_rec_date,      d.annual_rec_date,d.annual_cash,
     CAST(((b.ltp - a.ltp) / a.ltp * 100) AS DECIMAL(10, 2)) as chng
     FROM eod_stock AS a
    
     LEFT OUTER JOIN eod_stock AS b
     ON a.company_id = b.company_id
    
     LEFT OUTER JOIN company AS c
     ON c.ID = a.company_id
    
     LEFT OUTER JOIN dividend_info AS d
     ON c.ID = d.company_id AND d.interim_rec_date BETWEEN "2012-09-24" AND "2012-09-25" AND       d.annual_rec_date BETWEEN "2012-09-24" AND "2012-09-25"
    
     WHERE a.entry_date = "2013-09-24"
     AND b.entry_date = "2013-09-25"
     AND a.company_id IN (13, 2,4,5);
    

    Thanks Gordon Linoff for bring me on the track i was messing up with the right join
