按姓氏和名字排序

Question

I have a small little problem. I am have a drop down list that displays all of our customers names. As of right now, the list is sorted by last name (AZ). But for example, there are 250 people with the last name "Smith". What I need is a way that the last name of each customer to stay the way it is but I need the first names to be listed alphabetically as well. Here is an example:

Customer #1 - Smith, Jean
Customer #2 - Smith, Allen
Customer #3 - Smith, Davey

What I would like is this:

Customer #1 - Smith, Allen
Customer #2 - Smith, Davey
Customer #3 - Smith, Jean

Here is how I am pulling the list now:

SELECT customer_id, first_name, last_name FROM customers ORDER BY last_name

Answer 1

只需将您的ORDER BY子句更改为：

ORDER BY last_name, first_name

Answer 2

调整您的SQL语句，添加带有适当字段名称的ORDER BY子句：

ORDER BY last_name ASC, first_name ASC
