CountQueryBuilder <T>

SQL query builder with fluent interface.

const qb = orm.em.createQueryBuilder(Publisher);
qb.select('*')
  .where({
    name: 'test 123',
    type: PublisherType.GLOBAL,
  })
  .orderBy({
    name: QueryOrder.DESC,
    type: QueryOrder.ASC,
  })
  .limit(2, 1);

const publisher = await qb.getSingleResult();
