RANDOM

Returns a pseudo-random unsigned value greater than 0 and less than 1 of type DOUBLE PRECISION.

Syntax

RANDOM()

Return Types

DOUBLE PRECISION

Example

The example below demonstrates using RANDOM without any other numeric functions. This generates a DOUBLE PRECISION value less than 1:

SELECT RANDOM()

Returns: 0.8544004706537051

Example–using RANDOM for range of values

To create a random integer number between two values, you can use RANDOM with the FLOOR function as demonstrated below. a is the lesser value and b is the greater value.

SELECT
	FLOOR(RANDOM() * (b - a + 1)) + a;

For example, the formula below generates a random integer between 50 and 100:

SELECT
	FLOOR(RANDOM() * (100 - 50 + 1)) + 50;

Returns: 61
