Joining 3 tables in SQL and displaying columns from each

Question

I have three tables that all share a common ID and I wish to display columns from each of these tables by joining based on this common ID.

I am able to join two of the three tables but when I include the third I get errors.

This is my script:

select TableA.CommonID, TableA.Column1, TableB.Column2, TableC.Column3
from TableA
join TableB on TableA.CommonID = TableB.CommonID
join TableC on TableA.CommonID = TableC.CommonID;

What Am I doing wrong?

Answer 1

Try use InnerJoin to satisfy your requirement

SELECT a.CommonID, a.Column1, b.Column2, c.Column3
FROM TableA AS a
INNER JOIN TableB AS b ON a.CommonID = b.CommonID
INNER JOIN TableC AS c ON a.CommonID = c.CommonID
