Question

这是我的查询方法：

@Query(value = "select new com.twognation.hub.dto.GameDTO(game.id, game.name, game.active, game.description, game.coverImage, game.logo, game.backgroundImage, game.featuredImage, game.characterImage, game.smallCoverImage, count(tournament.id) as tournamentCount) from Game game left join Tournament tournament on game.id=tournament.game where lower(game.name) like '%:name%' group by game.id order by tournamentCount desc, game.id",
                countQuery = "select count(1) from Game game left join Tournament tournament on game.id=tournament.game where lower(game.name) like '%:name%' group by game.id order by tournamentCount desc, game.id")
Page<GameDTO> findAllOrderByTournamentCount(@Param("name") String name, Pageable page);

当我调用此方法时，出现此错误：

Answer 1

此：

'%:name%'

在JPA中，本地字符串是唯一的，要解决此问题，您可以像这样使用CONCAT运算符：

CONCAT('%', :name, '%')

例如，稍后将其转换为'%some_value%'

Answer 2

您似乎对like有疑问。

代替

'%:name%'

这样做：

%:name%
