Monthly UPI Volume Pivot by Type

SQL practice question · Medium · Aggregation · PhonePe, Paytm

Only status 'SUCCESS' transactions count. txn_type was typed by different services, so compare it case-insensitively and ignore surrounding spaces ('p2m ' is P2M). Return one row per month that has at least one successful transaction: month ('YYYY-MM'), p2p_amount, p2m_amount, bill_amount and total_amount (all successful transactions of any type, including other types such as RECHARGE). All amounts ROUND to 2 and 0 when there is nothing. Order by month.
