โรงพยาบาลที่มีอุณหภูมิต่ำสุดในปี 2105 คือเท่าไร?ไม่จำเป็นต้องใช้ทุกโต๊ะครับ
what's the minimum cost of a hospital with temperature in 2105?It is not neccessary to use all the tables.
 microlab:  microlabid [ number]  patientunitstayid [ number]  culturesite [ text]  organism [ text]  culturetakentime [ time] 
SELECT MIN(t1.c1) FROM (SELECT SUM(cost.cost) AS c1 FROM cost WHERE cost.patienthealthsystemstayid IN (SELECT patient.patienthealthsystemstayid FROM patient WHERE patient.patientunitstayid IN (SELECT lab.patientunitstayid FROM lab WHERE lab.labname = 'temperature')) AND STRFTIME('%y', cost.chargetime) = '2105' GROUP BY cost.patienthealthsystemstayid) AS t1
