Pick columns, sort, limit in SQL
SQL interview exercise on Select & Filter, 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.
Return the three cheapest products. Columns: name, price. Cheapest first; when two prices are equal, sort those 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.
