25,338 PointsChallenge task 2 relational databases SET OPERATIONS
The task is about finding 'name' from the respective 'vegetable' and 'fruit' table, but only finding the items that starts with the letter A through K.
my code looks like this;
SELECT name FROM fruit UNION SELECT name FROM vegetable WHERE name < "L";
i have no idea why this don't work, as it works with other tables in the SQL playground.

"Your UNION queries didn't bring back a union of fruits and veggies beginning with the letters A through K!"
I also have no idea why this doesn't work
