จนถึง 6 เดือนที่แล้ว ปริมาณ po cl liqs ของผู้ป่วย 008-19005 สูงสุดต่อเดือนคือเท่าใด? ไม่จำเป็นต้องใช้ตารางทั้งหมด
until 6 months ago, what was the monthly maximum intake of po cl liqs of patient 008-19005?It is not neccessary to use all the tables.
 intakeoutput:  intakeoutputid [ number]  patientunitstayid [ number]  cellpath [ text]  celllabel [ text]  cellvaluenumeric [ number]  intakeoutputtime [ time] 
SELECT MAX(intakeoutput.cellvaluenumeric) FROM intakeoutput WHERE intakeoutput.patientunitstayid IN (SELECT patient.patientunitstayid FROM patient WHERE patient.patienthealthsystemstayid IN (SELECT patient.patienthealthsystemstayid FROM patient WHERE patient.uniquepid = '008-19005')) AND intakeoutput.celllabel = 'po cl liqs' AND intakeoutput.cellpath LIKE '%intake%' AND DATETIME(intakeoutput.intakeoutputtime) <= DATETIME(CURRENT_TIME(), '-6 month') GROUP BY STRFTIME('%y-%m', intakeoutput.intakeoutputtime)
