Hi there
Does anyone know what's wrong with this code snippet:
SELECT md.ModelName, ca.VIN, ca.StickerPrice from Model AS md inner join Car AS ca on md.modelid = ca.carid;
Thanks, Gabriel

231,184 PointsThe JOIN keys should be columns in both tables that contain the same data. Comparing modelid in one table to carid in another won't be likely to return any data.
Hint: look for a column that both tables have in common and join using that.
