tell me the total amount of input that patient 5310 has received on last month/01?
select sum(inputevents_cv.amount) from inputevents_cv where inputevents_cv.icustay_id in ( select icustays.icustay_id from icustays where icustays.hadm_id in ( select admissions.hadm_id from admissions where admissions.subject_id = 5310 ) ) and datetime(inputevents_cv.charttime,'start of month') = datetime(current_time,'start of month','-1 month') and strftime('%d',inputevents_cv.charttime) = '01'
