This is quite simply a very bad idea. What is the point of the "Abc" in the user id? If you need a two part identifier, you should use a two column primary key instead where one is autoincrement and holds the numeric part while the second holds the alpha portion and is manually inserted with the insert statement. Much less of a coding headache this way and the work gets pushed to the db server.

My vote of 2: Way too much overhead in doing it this way and causes more problems than it solves. See my answer for a cleaner way to achieve this.
