Hi, this is a very easy question, but I don't seem to get it anyway.
I have table representing a SalesLineItem class, the table's name
is saleslineitem and is shown here below:

create table saleslineitem (
id int not null auto_increment primary key,
price double,
total double,
code text,
qty int,
name text,
description text
);

My question is, how to get the last id.
Suppose we have three rows inserted in that table, then the last id
is 3.
I want to retrieve the last id, but how?

select max(sli.id) from SalesLineItem sli
