Answer 1

这是一个解决方案。您还应该查看数据的显示方式（混合大小写）甚至长描述（例如 Epilepsy ABC）。

select i.patient_id, i.first_name, i.last_name, 
 coalesce(p.specialty,'not provided') as physician_specialty --coalesce in case you decide to left join at some point
from patients i
join admission a
  on i.patient_id = a.patient_id 
join physicians p 
  on a.attending_physician_id = p.physician_id
where upper(a.diagnosis) like '%EPILEPSY%'
  and upper(p.first_name) = 'LISA'

Answer 2

选择 p.患者 ID、p.名字、p.姓氏、d.专业 来自 AS p 患者 加入招生 ON p.患者_id =a.患者_id 加入医生 AS d ON a.attending_doctor_id =d.doctor_id 其中 a.diagnosis ='癫痫' AND d.first_name ='Lisa'
