DOUBLE PRECISION

Examples

Example

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

SELECT RANDOM()

Returns:

0.8544004706537051

Example

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;

The following code example generates a random integer between 50 and 100:

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

Returns

61
