| 28 | 16 | 6 | 2.00 |
| 33 | 3 | 2 | 1.50 |
| 34 | 16 | 2 | 4.00 |
+----+---------+------------+--------+
24 rows in set (0.00 sec)
From these tables I want to create a joined table that has the ID, Comment, Ingredient Name, and Number of ounces.
So far I have this query but I keep getting errors and I am not sure where I am going wrong.
select cocktail.comment
, drink.name
, mix.ounces
from cocktail
join mix
on mix.drinkID = drink.ID
join cocktail
on mix.cocktailID = cocktail.id;
I think that there is something wrong with my join statement but the MySQL error is ambiguous to me
ERROR 1066 (42000): Not unique table/alias: 'cocktail'
Would someone be able to provide me some guidance? Thank you!

Answer 1

You're query is calling the cocktail table twice. If you want to do that you need to use an alias to give unique names to the calls, but it looks like you're missing the JOIN to the drink table. It seems like you want:
select
c.comment,
d.name,
m.ounces
from drink d
inner join mix m
on m.drinkID = d.ID
inner join cocktail c
on m.cocktailID = c.id;
Here is a demo. This difference with this version and your version is it includes a call to the drink table to get the name of the ingredient.
