As stated in comments below the above does not work: If the first generated number (from the CTE anchor member) is a number already present in randomNums, then the CROSS JOIN of the recursive member will return NULL, hence the number from the anchor member will be returned...
Pseudo-random number generation involves the process of utilizing adeterministic algorithmthat produces a sequence of numbers whose properties approximately resemblerandom numbers. I sayapproximately resemble, because true randomness is a ratherelusive mysteryin mathematics and computer science. Hence, why the...

To generate a random number, in VBA, there is a function called RND. This function stands for random and when you use this function in code it returns a random number between 0 to 1. In RND, you don’t need to specify any argument. ...
The initial value of i should be a large odd integer. Each call to RAN gets the next random number in the sequence. To get a different sequence of random numbers each time you run the program, you must set the argument to a different initial value for each run. ...
