DatabaseValue

public struct DatabaseValue : Hashable, CustomStringConvertible, DatabaseValueConvertible, SQLExpression

DatabaseValue is the intermediate type between SQLite and your values.

See https://www.sqlite.org/datatype3.html

Extracting Value

  • Returns true if databaseValue is NULL.

    Declaration

    Swift

    public var isNull: Bool { get }

Hashable & Equatable

  • Returns whether two DatabaseValues are equal.

    1.databaseValue == "foo".databaseValue // false
1.databaseValue == 1.databaseValue     // true

    When comparing integers and doubles, the result is true if and only values are equal, and if converting one type to the other does not lose information:

    1.databaseValue == 1.0.databaseValue   // true

    For a comparison that distinguishes integer and doubles, compare storages instead:

    1.databaseValue.storage == 1.0.databaseValue.storage // false

    Declaration

    Swift

    public static func == (lhs: DatabaseValue, rhs: DatabaseValue) -> Bool
