「if」查詢mysql

Question

我想創建查詢。

select member.name,depratment.name from member 
left join depratment on depratment.dep_id=member.dep_id 
if(member.position_id=1){ 
where member.ages>50; 
} 
else{ 
where member.salary>50000; 
} 

幫幫我嗎？謝謝。

我想你不需要IF就可以了。你只需要一個複合條件。嘗試，

SELECT.. 
FROM.. 
WHERE (member.position_id = 1 AND member.ages > 50 ) OR 
     (member.position_id <> 1 AND member.salary > 50000)
