小编mle*_*eko的帖子

我使用实体管理器进行事务，确保我像这样调用的过程中没有嵌套提交，我设置了 ，search_path 因为我的过程在内部调用无前缀实体

async savetournamentTransaction(tournament: any, matchId: string) {
    await this.connection.manager.transaction(async (tournamentEntityManager) => {
      const tournamentRepository = tournamentEntityManager.getRepository(tournament);
      await tournamentRepository.query(`SET LOCAL search_path to ${matchId}`);
      await tournamentRepository.save(tournament);
      await tournamentRepository.query(
        `CALL fillOrganizationScheduleTable($1,${tournament.tournament_id});`,
        [matchId],
      );
    });
  }
}

然而，typeorm 给了我这个我无法真正理解的错误：
