Re: How to generate a unique 9 digit random id for every registered user?

2019-10-04 Thread אורי 
Hi,

In Speedy Net we generate a unique random ID with 15 digits and this is
used as the table's primary key. We don't use the DB's auto-generated ID.

The first digit of the random ID we generate is never zero.

Re: How to generate a unique 9 digit random id for every registered user?

2019-10-04 Thread Jani Tiainen 
Note that above solution doesn't guarantee unique id. As it is a problem of
any pseudorandom generator.

So it is possible (but unlikely) that insertion fails.

How to generate a unique 9 digit random id for every registered user?

2019-10-04 Thread yashwanth .k 
Hello,

My model consists of user details such as username and his id which is 
auto-generated by DB(indexing). 
Apart from this, I need to assign a random unique 9 digit number for every 
user.
The reason for assigning a random number to a registered user is to search 
a particular user using his permanent random id which we have generated.

Solutions with the model description will be very helpful.


Thank you!
