    Sum(if(t3.is_main="y", 1 ,0)) AS t3__5

INNER JOIN term_disease t2 ON (t2.disease_id = t.term_id) 
INNER JOIN term_disease_symptom t3 ON (t3.disease_id = t2.disease_id)
WHERE (t3.symptom_id in ( 45378 , 45351, 5546 ) AND t2.gender != 1  AND t2.active = 1 )
GROUP BY t3.disease_id
ORDER BY t3__5  desc;

Answer 1

Below

Sum(if(t3.is_main="y", 1 ,0)) AS t3__5 

sould be replaced with

SUM(CASE t3.is_main WHEN 'y' THEN 1 ELSE 0 END) AS t3__5
