Core Data and auto increment

Hi list !

I have a customer entity that contains a "customer number" attribute. I want this attribute to be automatically generated when a customer is inserted into the database (SQLite). In other words, I want the customer number attribute to auto-increment.

What's the best way to deal with this ? I'm currently fetching every customers of the database sorted by descending "customer number" and then I use the first customer of the array to compute the new customer number. But I'm wondering if there is not a best solution.

I've tried to use "customerNumber = max(customberNumber)" to retrieve the customer with the greatest customer number, but it doesn't work.

Any advice ?


Thanks,

Eric.
