In your WHERE clause, you can use inequality operators on string fields. For example, if compared a field named "word" using the expression "WHERE word < 'L'", you would get only words that start with letters that come before "L" in the alphabet ("A" through "K").

For more specific help, always show your code and also provide a link the course page you are working with.

Thank you, that worked. I had tried:

SELECT Name FROM Fruit WHERE Name IN ('A%','B%','C%', 'D%', 'E%', 'F%', 'G%', 'H%', 'I%', 'J%', 'K%') UNION SELECT Name FROM Vegetable WHERE Name IN ('A%','B%,'C%', 'D%', 'E%', 'F%', 'G%', 'H%', 'I%', 'J%', 'K%') ORDER BY Name;

as well as trying to use

WHERE Name BETWEEN 'A' AND 'L'

Surprisingly those didnt work.

You can't use wildcards with "IN", they only work with "LIKE".

But you originally asked for only names "with the letter L to Z". Check my answer again, I revised the example to fit this new criteria.
