Example

Let's create a table students with columns id, name, and score, and insert some data:

CREATE TABLE students (
  id INT,
  name VARCHAR,
  score INT
);

INSERT INTO students (id, name, score) VALUES
  (1, 'Alice', 80),
  (2, 'Bob', 75),
  (3, 'Charlie', 90),
  (4, 'Dave', 80);

Now, we can use ARG_MIN to find the name of the student with the lowest score:

SELECT ARG_MIN(name, score) AS student_name
FROM students;

Result:

| student_name |
|--------------|
| Charlie      |
