SQL Challenge using DATE() correctly.

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.

SELECT COUNT(status) FROM orders WHERE status = "shipped" AND DATE("now");

I'm not quite sure where my code is wrong, the count I am getting seems to be all things no matter the WHERE. What's the correct solution?

You didn't link to the challenge, so I can't check to be certain. But I do see a couple of issues:

  • You forgot the instruction that says: "Alias it to shipped_today."
  • "DATE("now")" isn't a comparison. You probably meant: "ordered_on = DATE("now")"

Looks like putting "ordered_on" = DATE("now") was the correct thing. I think the issue I was having was, when it says count total number of orders that have the status of shipped today I didn't assume that things that were ordered today were also shipped today. Thank you!
