Използвайте ROW_NUMBER()
прозорец функция за получаване на реда с Run_amt
от максималния месец и след това с условно обобщаване:
SELECT t.ID, t.Name, t.Amount,
MAX(CASE WHEN LAST_DAY(Date) = LAST_DAY(CURRENT_DATE) THEN cal_amt END) cal_amt,
MAX(CASE WHEN t.rn = 1 THEN Run_amt END) Run_amt
FROM (
SELECT *,
ROW_NUMBER() OVER (PARTITION BY ID, Name, Amount ORDER BY Date DESC) rn
FROM tablename
) t
GROUP BY t.ID, t.Name, t.Amount
Или:
SELECT t.ID, t.Name, t.Amount,
MAX(t.cal_amt) cal_amt,
MAX(t.Run_amt) Run_amt
FROM (
SELECT ID, Name, Amount,
MAX(CASE WHEN LAST_DAY(Date) = LAST_DAY(CURRENT_DATE) THEN cal_amt END)
OVER (PARTITION BY ID, Name, Amount ORDER BY Date DESC) cal_amt,
FIRST_VALUE(Run_amt) OVER (PARTITION BY ID, Name, Amount ORDER BY Date DESC) Run_amt
FROM tablename
) t
GROUP BY t.ID, t.Name, t.Amount
