OrderedRequest

The protocol for all requests that can be ordered.

  • order(_:) Default implementation

    Creates a request with the provided orderings promise.

    // SELECT * FROM player ORDER BY name
var request = Player.all()
request = request.order { _ in [Column("name")] }

    Any previous ordering is replaced:

    // SELECT * FROM player ORDER BY name
request
    .order{ _ in [Column("email")] }
    .reversed()
    .order{ _ in [Column("name")] }

    Default Implementation

    Creates a request with the provided orderings.

    // SELECT * FROM player ORDER BY name
var request = Player.all()
request = request.order(Column("name"))

    Any previous ordering is replaced:

    // SELECT * FROM player ORDER BY name
request
    .order(Column("email"))
    .reversed()
    .order(Column("name"))

  • Creates a request that reverses applied orderings.

    // SELECT * FROM player ORDER BY name DESC
var request = Player.all().order(Column("name"))
request = request.reversed()

    If no ordering was applied, the returned request is identical.

    // SELECT * FROM player
var request = Player.all()
request = request.reversed()

  • Creates a request without any ordering.

    // SELECT * FROM player
var request = Player.all().order(Column("name"))
request = request.unordered()

OrderedRequest

  • order(sql:arguments:) Extension method

    Creates a request sorted according to sql.

    // SELECT * FROM player ORDER BY name
var request = Player.all()
request = request.order(sql: "name")

    Any previous ordering is replaced:

    // SELECT * FROM player ORDER BY name
request
    .order(sql: "email")
    .order(sql: "name")
  • order(literal:) Extension method

    Creates a request sorted according to an SQL literal.

    // SELECT * FROM player ORDER BY name
var request = Player.all()
request = request.order(literal: "name")

    Any previous ordering is replaced:

    // SELECT * FROM player ORDER BY name
request
    .order(literal: "email")
    .order(literal: "name")
