rand

The rand function generates a random float, between 0 and 1.

API DEFINITION
rand() -> number

The following example shows this function, and its output, when used in a RETURN statement:

RETURN rand();

The following example shows this function being used in a SELECT statement with an ORDER BY clause:

SELECT * FROM [{ age: 33 }, { age: 45 }, { age: 39 }] ORDER BY rand();


[
{
age: 45
},
{
age: 39
},
{
age: 33
}
]

rand::bool
