    ReQL command: not

    Command syntax

    bool.not() → bool

    r.not(bool) → bool

    Description

    Compute the logical inverse (not) of an expression.

    not can be called either via method chaining, immediately after an expression that evaluates as a boolean value, or by passing the expression as a parameter to not. All values that are not false or null will be converted to true.

    Example: Not true is false.

    r(true).not().run(conn);
    r.not(true).run(conn);
    

    These evaluate to false.

    Example: Return all the users that do not have a “flag” field.

    r.table("users").filter(user -> user.hasFields("flag").not()).run(conn);
    

    Example: As above, but prefix-style.

    r.table("users").filter(user -> r.not(user.hasFields("flag")).run(conn);
