Successful Payments by Order

Reconciliation searches payments for rows with status = 'success' for a specific order_id. Add an index that supports both fields: status first, then order number.

Speed this query up with an index
CREATE INDEX ix_payments_status_order ON payments (status, order_id)

Ainult CREATE/ALTER/DROP — lõpus pole vaja SELECT-i.
