What is wrong with my code?

"In an ecommerce database there's an orders table with the columns id, product_id, user_id, address_id, ordered_on, status and cost. Count the total number of orders that have the status of shipped today. Alias it to shipped_today"

I entered this but I do not understand what is wrong

select count(*) from orders where status = "shipped" and date("now");

I was struggling a bit too but i think it should be

SELECT COUNT (*) AS shipped_today WHERE status = "shipped" AND ordered_on IS DATE("now", "- 1 day");

Yes, Steven is correct. For visual learners, the below will work: SELECT COUNT(*) AS shipped_today FROM orders WHERE status = "shipped" AND ordered_on = DATE("NOW"); Enjoy.

You forgot the alias, and your date comparison is incomplete.

It looks like junescano got closer, but you wouldn't use "IS" to compare dates (just a regular "=").

Also, if you're looking for "today" you wouldn't add that extra argument to subtract a day. That would be if they had asked for "yesterday" (which I think they do in a different challenge).

In future, always include a link to the course page to facilitate the most accurate answers.
