1,962 PointsSubquery using IN
These subquery lessons have me super confused. I've copied and pasted my code below, it keeps saying I can't use more than 1 column in my subquery....
SELECT ModelName FROM Model WHERE StickerPrice IN (SELECT StickerPrice FROM Car WHERE StickerPrice < '$30,000');

- the subquery can filter on StickerPrice, but it must SELECT a column that both tables have in common
- the outer query will then filter using the common column
- the StickerPrice will be a number, not a string
