ReQL command: not

Command syntax

bool.not() → bool

r.not(bool) → bool


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.


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);
