Code Challenge Task 3

A bit stumped on how this is wrong... The error says my union statement doesn't return all values including duplicates... But I'm using UNION ALL.

You need to show your entire statement for us to be able to identify the issue and help resolve it.

Text of a challenge: 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!

Code should look like: SELECT Name FROM Fruit UNION ALL SELECT Name FROM Vegetable ORDER BY NAME ASC;

It's possible you did not include ORDER BY part, for most of these tasks site logic will look for exact match in your answer and sometimes error you get do not pinpoint your problem.
