I want insert values in sql server.
C#.net: GUIDs are not random, they are only unique (within a single system). Even a random number generator has limits on it, the minimum and maximum values it will return, and being truly random in sql server(insert values into the table).please say refer Website.

Thanks Advance Friends.

Your question is not complete. You complain about the built-in random number generator, but you don't define the randomness in your terms. The "limitation" that the random function has a maximum is not a limitation. Just as example: how could you store a random number of arbitrary length in a fixed length field? So first of all define your purposes. Since you looked around at GUID, you probably need more a random string than a single number. Does it have to be cryptographic or a general one?

So, what do you want? You want random numbers? Where are you stuck?

Solution 1

RANDOM.org might help. However, "truly" random numbers are impossible to generate - you need to find the best pseudo-random generator you can.

Take a look at the RNGCryptoServiceProvider class (http://msdn.microsoft.com/en-us/library/system.security.cryptography.rngcryptoserviceprovider.aspx[^])it is generating strong pseudo-random numbers based on a cryptographic algorithm.
I would say this is as "truly" random as you can get in software.
