The HSP_TRANSACTIONS table has one row for every transaction. If, and only if, a transaction is a refund to a coverage, it identifies the coverage with the RFND_COVERAGE_ID column. Not all refunds are to coverages, and not all coverages are refunded.

Use the following query to answer the question below it:

SELECT * FROM HSP_TRANSACTIONS COVERAGE ON HSP_TRANSACTIONS.RFND_COVERAGE_ID=COVERAGE.COVERAGE_ID

What should replace < your SQL here > to return only refunds to coverages?
