Don't.
Stop and think about it.
Why are you showing the value at all? So that people know what value will be assigned to the new record they are creating. But the main reason for using SQL is that it supports multiple users at the same time, so the "next value" won't be the next one - that value may have been used by a different user two hours ago.

That leads to confusion - only show information when it will be correct - which in the case of auto incremented data is only after the record has been inserted correctly.

If you need to give the user the record id, then there is probably something wrong with your data design.
