Join Query with SQL

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

Trying to join three tables together, keep getting: "ambiguous column name ModelName. Is this an outer join or is my syntax incorrect? Thanks!

Assuming this is for task 2, the message is a bit misleading.

The actual issue is a syntax error caused by a stray comma and the word "Model" before the last "INNER JOIN".

SELECT Model.ModelName, Car.VIN, Car.StickerPrice FROM Model INNER JOIN Car ON Model.ModelID = Car.ModelID;

should do.

This will pass for task 1, but it's not necessary to qualify the column names in the SELECT clause because they are all unique.
