I'm finding an auto-increment field (part of a compound primary key) updates

The count happens after the where on an index - it should just count the
appropriate index rows without looking at the values. Worth benchmarking on

I think ideally I would like to create an auto increment column that

That can't be done. An auto-increment value must be higher than the

because a field is auto-increment, doesn't mean you can't enter you

Do you mean you want to be able to display the record number as sorted by
the auto-increment field, rather than the auto-increment field itself? Or do
you just want the total number of records? Or do you just want the highest
current value of the auto-increment field?
The latter two are easy

Hi, I'm looking for some basic help. I am developing a MySQL database and
want to auto increment a field, but I don't want it to just count 1,2,3,

Hello,
you can do it in two ways I guess:
one is to do a second select (which you don't want):

Hi, im hoping to solve a problem that is bugging me!
