This syntax allows the ORDER BY clause to include column names rather than positionally defining the sort columns. The AS keyword is not included when column_2 is renamed to second_value.

SELECT COLUMN1 +100 AS first_value, column_2 second_value
FROM table_1
WHERE second_value > 100
ORDER BY first_value;
