Question

I need to write a query to select products from a database for a search page, at the moment the query is really simple

SELECT * FROM products WHERE stock > 0 ORDER BY id DESC

This query brings back products fine starting from the newest, we will be going into sale soon so I need to change the query to order by the newest product on sale descending, then go onto display the remaining products that aren’t on descending. If a product is on sale rrp is not equal to 0. Is there a way where I can do this without having to run two separate queries?

Is was thinking something like

SELECT * FROM products WHERE stock > 0 ORDER BY (rrp != 0) DESC, id DESC

but that doesn’t work.

Thanks in advance

try this:

SELECT * 
FROM products 
WHERE stock > 0 
ORDER BY 
Case when rrp != 0 then 0 else 1 end,
id DESC
