I need help please! What am I doing wrong?

Task 2 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 all fruits and vegetables starting with the letters A through K . In other words all fruit and vegetables that don't start with the letter L to Z."

I have reproduced the following SQL query:

SELECT Name 
FROM Vegetable 
WHERE Name LIKE "[a-k]%"
UNION 
SELECT Name 
FROM Fruit 
WHERE Name LIKE "[a-k]%";

What am I doing wrong?

Thanks!

Hi there, Lucio Bonforte! I see that you've put some time and thought into this. First, it's going to require that you return DISTINCT fruits and vegetables. There can be items that end up on both lists. Secondly, you're trying to use LIKE here, but what you need is < "L". The "[a-k]%" is not going to work. This was my solution:

SELECT DISTINCT(Name) 
FROM Vegetable 
WHERE Name < "L"
UNION 
SELECT DISTINCT(Name) 
FROM Fruit 
WHERE Name < "L";

Hope this helps! :sparkles:

Hi Jennifer, so we can't use wildcards in the team treehouse database?
