Challenge Task 1 of 4 In a car database there is a Model table with columns, ModelID, MakeID and ModelName and a Car table with columns, CarID, ModelID, VIN, ModelYear and StickerPrice.
Use a subquery along with IN to list all the Model Names with a Sticker Price greater than $30000
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 md.ModelName, ca.StickerPrice FROM Model AS md INNER JOIN Car AS ca ON md.ModelID = ca.ModelID WHERE StickerPrice IN (SELECT ca.StickerPrice FROM Car WHERE caStickerPrice> 30000);

No need for the join since you will be using a subquery instead.
I would use a key in the subquery - the common field between the two tables.
You only need to select the ModelName in the main query
