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();

    Returns SelectQueryBuilder<T>

execute

  • execute<U>(method?: get | all | run, mapResults?: boolean): Promise<U>
  • execute<U>(method: all, mapResults?: boolean): Promise<U>
  • execute<U>(method: get, mapResults?: boolean): Promise<U>
  • execute<U>(method: run, mapResults?: boolean): Promise<U>

  • Executes this QB and returns the raw results, mapped to the property names (unless disabled via last parameter). Use method to specify what kind of result you want to get (array/single/meta).

    • T: Partial<T> = Partial<any>

    Parameters

    Returns QueryBuilder<T>

getCount

  • getCount(field?: string | string[], distinct?: boolean): Promise<number>

getParams

  • getParams(): readonly Value[]

  • Returns the list of all parameters for this query.

    Returns readonly Value[]

getQuery

  • getQuery(): string

  • Returns the query with parameters as wildcards.
