Returns a pseudo-random unsigned value greater than 0 and less than 1 of type
The example below demonstrates using
RANDOM without any other numeric functions. This generates a
DOUBLE value less than 1.
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;
