Wow, I keep getting stumped! This might not be for me! I'm trying hard though, this challenge is kicking my butt!

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 were ordered yesterday and have the status of 'shipped'. Alias it to ordered_yesterday_and_shipped.

Type in your command below, then press Ctrl-Enter.

Bummer: There's something wrong with your SQL statement. Please review your code and try again.

SELECT COUNT(*) AS ordered_yesterday_and_shipped FROM orders WHERE ordered_on DATE("now", "-1 day");

I receive this error "Bummer: You're count calculation was wrong. Was expecting the count of 14." with the following statement: SELECT COUNT(*) AS "ordered_yesterday_and_shipped" FROM orders WHERE status = "shipped" AND ordered_on = DATE("now", "-1day");

@theresa smiley You need a space between -1 and day

You missed the status clause and need an equals sign in your date clause like this:

SELECT COUNT(*) AS ordered_yesterday_and_shipped FROM orders WHERE ordered_on = DATE("now", "-1 day") AND status = 'shipped';
