Random seed genarator with eight positive number

ZahidHussain — Mon, 26 Jul 2021 16:27:53 GMT

Hi Folks,

I want to generate random seed number for subject id such as

subject id seed

12345678 21258793

47582236 32569874

My subject id is 8. . Each seed would be 8. and random seed would be fixed for each subject id. How to write that code?

Thanks

zahid

Thanks for your reply. Does every time generation those random number would be same?

If the seed and data is exactly the same, ie order then yes. But if you're asking if you pass in 12345678 will you always get the same value out, the answer is No. Any solution that does that is considered reversible essentially as soon as you have a few mapped and unmapped IDs.
