Challenge task 2 from the Joining Table Data With SQL section. I get: SQL Error: no such column: MakeName.

I’m trying to complete challenge task 2 from the Joining Table Data With SQL section of the Querying Relational Databases course.

Here’s the challenge text: “In a car database there is a Make table with columns, MakeID and MakeName, a Model table with columns, ModelID, MakeID and ModelName and a Car table with columns, CarID, ModelID, VIN, ModelYear and StickerPrice. For all cars in the database, show Make Name, Model Name, VIN and Sticker Price from the Model and Car tables in one result set.”

I’ve written the following SQL:

SELECT MakeName, ModelName, VIN, StickerPrice FROM Model INNER JOIN Model ON Make.MakeID = Model.MakeID INNER JOIN Car on Model.ModelID = Car.ModelID;

and I get the following error: SQL Error: no such column: MakeName

You're joining the Model table to itself (and then to Car), but it looks like you intended to join the Make table to Model and Car.

Changing "... FROM Model ..." to "... FROM Make ..." should resolve the issue.
