Booleans

Boolean values can be used to mark whether a field is true or false.

CREATE person SET newsletter = false, interested = true;

Many SurrealDB operators and functions return booleans.

CREATE person SET 
    name = "Billy", 
    name_is_billy = name = "Billy",
    name_is_long = string::len(name) > 10;

Response
[
    {
        "id": "person:8ii7v7f54a2m1rla1y6b",
        "name": "Billy",
        "name_is_billy": true,
        "name_is_long": false
    }
]

Boolean values can be written in anycase.

CREATE person SET 
    newsletter = FALSE,
    interested = True,
    very_interested = trUE;
