表1：Attendee_Login
列：id_event, login_id(primary key),attendee_status
表2：Decline_Handshake
列：id_handshake(primary), id_event, from_id(foreign key of Attendee_Login.login_id), to_id(foreign key of Attendee_Login.login_id)
我要查询
(Attendee_Login.login_id,
count(Decline_Handshake.from_id == Attendee_Login.login_id), count(Decline_Handshake.to_id == Attendee_Login.login_id)
)
条件是Decline_Hanshake中的外键在attendee_status == 0表中必须有Attendee_Login。
我可以知道怎么做吗？我尝试为from_handshake和to_handshake创建2个子查询并加入主查询，但最终以相同的结果填充所有Attendee_Login.login_id
