I want a field in my table to autoincrement like 'CHD0001', 'CHD0002',
'CHD0003'

Why does the CHD prefix need to be there? Will it ever change?

If not it's unnecessary. It can be generated when you query the column
or with a view.

If yes, it should be a separate column.

Can't do it straight. Can CONCAT('CHD', CAST(my_id as CHAR)) on select
though, where my_id is your autoincrement, zerofill int(5) column.

If CHD is there for presentational purposes only, I would prefer putting
it into the presentation (or logic) layer instead of using the database
to do that.
