I have 3 tables and some fields' names are the same. Here is the first table named semp :
The second one's name semp_k :
And the third is semp_y :
You see, the main table is the first and the others are related it. The first table has got 3 row. So when I fetch it, it must return 3 row. But when I fetch the first table, it multiples returned rows with sum of second and third table. Here is my code:
SELECT s.*, k.*, y.* FROM semp AS s LEFT JOIN semp_k AS k ON s.no = k.semp_no LEFT JOIN semp_y AS y ON s.no = y.semp_no WHERE s.durum = 1 ORDER BY s.bas_t DESC
use MySQL group by
group by s.no
or try this :-
SELECT
s.*, k.*, y.*
FROM
semp AS s
LEFT JOIN semp_k AS k ON s. NO = k.semp_no
LEFT JOIN semp_y AS y ON s. NO = y.semp_no
WHERE
s.durum = 1
GROUP BY s.no
ORDER BY
s.bas_t DESC
You need to use group by. Your query should be like this ;
SELECT
s.*, k.*, y.*
FROM
semp AS s
LEFT JOIN semp_k AS k ON s. NO = k.semp_no
LEFT JOIN semp_y AS y ON s. NO = y.semp_no
WHERE
s.durum = 1
GROUP BY s.no
ORDER BY
s.bas_t DESC
