So I would consider random to be very portable. It is faster to allow OpenSSL to generate more random numbers from a seed. For integers, we want to avoid modulo bias. Just last year, a cryptolocker-type virus on Linux made the mistake of seeding with the time, and this dramatically reduced the search space. I used djb2 as my hash function. If your system supports the arc4random family of functions I would recommend using those instead the standard rand function. Windows , then use rand or some internal Windows specific platform-dependent non-portable API. Random describes algorithms for removing bias from random integers, and packing 53 bits into random floats. Beitrags-Navigation 1 2 Next.

This sqlfiddle shows, that duplicates are created for three character long strings. But i need only one example of duplicates to disprove this concept.

For the IDs and your algorithm will generate the same string T82X demo. Another solution for generating an 8-character long pseudo-random string in pure My SQL: Thanks for your solution i have one question regarding UUID.

Please note that the first 8 characters of UUID is not random, but sequential, since it is based on the timestamp. MartinAJ because the string is a uuid.

You can easily replace the hyphens e. Good idea, could use it on the primary key. Will keep this in mind for future projects, thanks!

This is of course only toy randomness. It is not random at all. You could make it more "random" if instead of using the auto incremental id, you use the datetime in which the insert was done, which is also unique.

You can customize the allowedChars. Check if the random string is already in use If we want to keep the collision checking code out of the app, we can create a trigger: Paddy Mann Paddy Mann 8 Here is one way, using alpha numerics as valid characters: Gordon Linoff Gordon Linoff k 35 Andrey Volk Andrey Volk 3, 2 11 You can generate a random alphanumeric string with: Paul Spiegel Paul Spiegel This is exactly what I wanted.

I only would like to understand how it gets converted to a string. Why is there a pow, what to do, to add numbers and so on.

Akxe conv can be used to convert a number to an alphanumeric string. You sir are a genius. I need to put the five letters back together.

How do I do that? Well, I need to join them, so I use the —Join operator and put the rest of the code in a pair of parentheses:. Now when I run the code, I get a single line of five random letters that is made up of upper and lower case letters of the alphabet:.

BG, that is all there is to creating a random string of letters. Join me tomorrow when I will talk about more way cool stuff. I invite you to follow me on Twitter and Facebook.

If you have any questions, send email to me at scripter microsoft. You must be logged in to post a comment. This solution is a bit limited, since every letter can occur at most once.

Something better is e. Plus numbers and symbols: Poking around for something a bit more readable, I came up with the following, which use regular expressions to do the character class limits rather than hard-codes ASCII code points.

Letters, numbers, and punctuation: Added the ability to get same character more than once: Five random letters in one line I can create a five random letter word with a single line of Windows PowerShell.

The command uses the Count parameter: Get-Random -Count 5 Because the Get-Random cmdlet loves pipelined input, all I need to do is add a pipe character after my array of numbers and before Get-Random: This is shown in the following image:

However, as the number of vehicles increases, I expect this to become even more inefficient it is right now. The query I need should simply generate a 8-character alphanumeric string which is not already in the table.

While randomness is quite easily achieved, the uniqueness without a retry loop is not. This brings us to concentrate on the uniqueness first.

So using a uniqueness-preserving, pseudo-random transformation would be fine:. Just generate a random string and check if it exists.

What about calculating the MD5 or other hash of sequential integers, then taking the first 8 characters.

I have no idea how many you could allocate before a collision but it would be a known and constant value. This is now an old answer, but I saw it again with time on my hands, so, from observation That works this way if the column allows NULLs.

But the trigger will take care of uniqueness. Taking into account the total number of characters that you require, you would have a very small chance of generating two exactly similar number plates.

Thus you could probably get away with generating the numbers in LUA. For a String consisting of 8 random numbers and upper- and lowercase letters, this is my solution:.

Make your voice heard. Take the Developer Survey now. Any help is appreciated. How random do you need these to be?

If someone receives a particular license plate, is it important or not whether they can work out the next or previous license plate that you handed out?

This problem consists of two very different sub-problems: So using a uniqueness-preserving, pseudo-random transformation would be fine: Hash has been suggested by paul AES-encrypt fits also But there is a nice one: Eugen Rieck Eugen Rieck How can we be sure that 8 successive calls to rand are guaranteed to return a different sequence if initialised with a different seed?

I was just wondering. Because I now have a single array of numbers with my range, I can pipe the output from that range to the Get-Random cmdlet and tell it to select five numbers for me.

The command uses the Count parameter:. Because the Get-Random cmdlet loves pipelined input, all I need to do is add a pipe character after my array of numbers and before Get-Random:.

I can test that the command works by highlighting the code in the ISE and running only the selected code. This is shown in the following image:.

Now all I need to do is to accept the pipelined input from the Get-Random portion of the code. It is the [CHAR] part that has the issue.

It will now take each object that comes across the pipeline and do whatever I put into my script block. What is up with that?

I need to put the five letters back together. How do I do that? Well, I need to join them, so I use the —Join operator and put the rest of the code in a pair of parentheses:.
