Question

I have a simple query which queries by item_id and it obviously works because it is so simple.

What I need to do is change it to also take into account the updated date, and be something similar to this:

 select item_id , item_name from items order by item_id , update_date desc limit 200

So the requirement is:

• Order by update_date and tie break by item_id.
• Where update_date is null, just rank it by item_id.

How can I do that?

Thanks!

When your sorting, SQL will sort by the order the fields are listed in the query in succession, so in the below example

select item_id , item_name, update_date, from items order by update_date desc , item_id  desc;

it will order by update_date first, then order those(sorted) results by item_id, both descending.
