Bucket values with CASE in SQL
SQL interview exercise on Strings, Dates & CASE, difficulty 1 of 3. Solve it in the editor beside a worked example, or cold in Interview mode with the example hidden; the tests run the moment you do.
Give every product a price band: 'budget' under 50, 'standard' from 50 up to but not including 200, 'premium' from 200 up. Columns: name, band. Sorted by name.
Each exercise pairs a worked example with a twin problem to solve in a real editor; the tests run the moment you do. Interview mode hides the example: solve it from memory, without the hint or the solution, and it counts as solved cold. Progress is saved in your browser, and in your account if you sign in.
