To create a random integer number between two values, you can use RANDOM with the FLOOR function. If a is the lesser value and b is the greater value, compute FLOOR(RANDOM() * (b - a + 1)) + a. The following code example generates a random integer between 50 and 100:

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