Random

The Random() generates a random number.

This function is NOT SQL compatible. For more information about SQL compatibility, see our documentation.

Returns a random integral number between 0 or a specified minimum value, and a maximum value. Returns Invalid expression if one of the parameter values is not a valid number, or is a negative number, or when a maximum value is 0, or when the maximum value is less than the specified minimum value or 0 when only the maximum is specified.

As of version 4.2, the Random function also accepts negative numbers when both min and max values are provided - just as long as min < max.

This function uses 32-bit Integers, therefore the range of valid parameters is
