Hi

We need to generate a security number for all records and the security number should be unique.

Eg: Security 1 -- > AB001
Security 2 -- > CF345

ETC..

Need a unique number and the number should not go out of series for minimum 10 years..

Please help to provide any solution.

Eg: A0001 , A0002 , A0003 AB001, AB002

numr,

Why dont you generate sequence number (like 00000,00001 etc..). Once you reach '99999' generate alphanumeric numbers.

You need to put your effort for this and dont expect we will do 'your work'. If you face any problem, we are here to help you.

is this some kind of homework...

I would say that relying on forum replies for security related question is not a company wise approach..

even ATM application rely on a 5 all numeric digit and do not require uniqueness..

Review Your security needs,
use a longer string,
use some kind of ashing technique
review the uniqueness requirement

have somebody review/audit Your organization security
