Question

I have two tables as following

table one named tbooking having column fields as booking_ref_id, date_created

table two named tpayment_transaction having column fields as payment_txn_ref_id, booking_ref_id, payment_status

I have to write a query for “Number of transaction per status per year”

the result should be like —

 payment_status     count       date_created
1 Progress            34         2011
2 Completed           10         2012

and so on….

since threre are 4 type of payment_status

Answer 1

I’m assuming tbooking.date_created is some kind of date field. If it’s a string field with the actual year like ‘2011’, then you can exclude the YEAR() function:

SELECT payment_status, COUNT(*) AS count, YEAR(tb.date_created) AS date_created
FROM tpayment_transaction tt
JOIN tbooking tb
  ON tb.booking_ref_id = tt.booking_ref_id
GROUP BY tt.payment_status, YEAR(tb.date)
