5,886 PointsUNION ALL didn't bring back a union of all fruits and vegies (Querying Relational Databases, Challenge 3 of 6)
Hi,
In the Querying Relational Databases Class, my UNION ALL query didn't bring back a union of all fruits and vegetables.
Here's the question: Challenge 3 of 6:
There are two tables Fruit and Vegetable table. The Fruit table has a FruitID and a Name column and the Vegetable table has a VegetableID and Name column. Create a list of fruits and vegetables that includes any potential duplicate values. Ensure that it is in alphabetical order so that the duplicates are next to each other!
Here's my query:
SELECT Name FROM Fruit UNION ALL SELECT Name FROM Vegetable ORDER BY Name DESC; I got a table listing Zucchini, Zucchino, Yams, Winter Melon
And I got the following error message:
Bummer! Your UNION queries didn't bring back a union of all fruits and veggies (including duplicates).
My query appears to follow the UNION ALL format. I made sure to use the same columns on each side (Name). I'm not sure why I'm getting this error message. Any ideas?
Thanks,
Jan

The challenge said, "Ensure that it is in alphabetical order" but your query specifically returns reverse alphabetical order using the DESC
keyword.
Try it without "DESC
".

5,886 PointsHi Steven,
Thanks for the feedback. From that error message, I wouldn't have thought that's what it was.
You were right. Great catch!
Thanks,
