Generating a unique random number

how to generate a random number which has not been already generated for
any previous entry, i.e. each time I do a new entry in the form it should
generate a unique random number which has not been already used.

I think the random() function is what you are looking for. It is documented
here:

Thanks!

Hi Anu,

Just to clarify Abhishek's email, the random() function will generate a
random number but it *won't *guarantee that the number has not been used
before.

If you're using case management in your application (
Case Management - CommCare Public - CommCare Public), then
we will automatically generate a 32 character unique identifier for each
case.

What are you using this random number for?

Thanks,
Sheel
