15,163 PointsThee Inner Join Syntax - what am I missing?
SELECT MakeName, ModelName, VIN, StickerPrice FROM Make INNER JOIN Model ON MakeID WHERE Make.MakeID = Model.MakeID INNER JOIN Car ON ModelID WHERE Car.ModelID = Model.ModelID;
SQL Error: near "INNER": syntax error
What's wrong?

231,248 PointsYour JOIN
syntax is a bit off.
Where you have:
... INNER JOIN Model ON MakeID WHERE Make.MakeID = Model.MakeID ...
The ON
expression is not complete, and you would not put a WHERE
clause before another JOIN
. So you probably meant something like this:
... INNER JOIN Model ON Make.MakeID = Model.MakeID ...
The same changes would be applicable to the other JOIN
.
Next time be sure to include a link to the course page to enable the most accurate analysis.

15,163 PointsThanks. I figured it out. Just need to remove the WHERE when using multiple INNER JOINs.
SELECT MakeName, ModelName, VIN, StickerPrice FROM Make INNER JOIN Model ON Make.MakeID = Model.MakeID INNER JOIN Car ON Car.ModelID = Model.ModelID;
