Humor me!! This is SQL Rand. If you call it in quick succession for a range it might generate the same number. Well, that is not the case. There are no quick succession (24 hours period) and there is no fixed range (count of tickets).

In earlier days I was using RAND with NEWID (a GUID if you like) and CHECKSUM  for the NEWID to generate the random number. Do not take my words, go for a test. Run a million random numbers with either method. Just make sure they are not in succession.

I am not having a go at you over this matter Tia in fact I was letting the subject drop until you challenged me.

You are in line for the Nobel prize for science as you have managed to do what no one else has ever been able to do since Babbages analytical engine. No one at Oxford, Cambridge, MIT or any computer laboratory anywhere in the World has ever managed to generate a true random number with any computer program in any computer programming language with out using quantum effects.

You may dispute my opinion that your program will never generate true randomness. This is too the good as any debate usually leads to improvement no matter what is debated.  I am only going off experience that from when I started to learn to program in various computer languages in 1972 on a dumb terminal using a dedicated phone line hooked up to an Elliott 803 and a PNP-8 hybrid computer, and building my first kit computer in 1975 (Altair 8800) for home use.  I have had pseudo random numbers generated by computers.

All of the research papers over true random vs pseudo random number generation are all available on line.

You are not helping anyone with this Slapper. Being sarcastic because someone won a 5 PED twice??

This was the attitude of some regular whiners earlier and raffles had to go. Maybe you need to rethink.

I believe that that guy doesn't understand the nature of random numbers and the triple-layered randomness there's within the raffles.
