I have these two tables
And I am using this query to get the results
@Query(value = "SELECT bet.bet, match.name, match.week FROM bet INNER JOIN match ON match.id=bet.match_id WHERE match.week = ?1", nativeQuery = true) List<Object[]> customQuery(Long week);
So far this is the only way I could retrieve the results and actually use them later. To use them I am using this code currently
List<Object[]> bets = gr.customQuery(2l); for (Object[] object : bets) { int bet = (BigInteger) object[0]; String name = (String) object[1]; int week = (BigInteger) object[2]; System.out.println(bet + " " + name + " " + week); }
But using it that way seems odd to me. Is there a better way to directly map the result to a DTO or something…

There are some options. The most straighforward way would be to define a projection Interface, like:
public interface BetDTO { Long getBet(); String getName(); Integer getWeek(); }
With that you could change your query return type to:
List<BetDTO> customQuery(Integer week);
The rest would then be using getters.
