SQL Order By

To sort your result records, use ORDER BY construction. There is a syntax of query:

-- do not run this query
SELECT col1, col2, ...
FROM table
WHERE condition
ORDER BY some_col1, some_col2, ... 

              
12345

            
-- do not run this query
SELECT col1, col2, ...
FROM table
WHERE condition
ORDER BY some_col1, some_col2, ...
copy

ORDER BY is at the end of the query, and sorts by one or multiple columns in their order. For example, if there is a construction ORDER BY singer, title, the result will be sorted by singer's name, but for multiple songs of the same singer, records will be sorted by title.

By default, sorting is in ascending order, but you can define it. Use ASC and DESC keywords after each column name:

SELECT id, title, year
FROM songs
ORDER BY year DESC

              
123

            
SELECT id, title, year
FROM songs
ORDER BY year DESC
copy

ASC or DESC statement relates to the column name before it. It means, that in ORDER BY title ASC, price DESC first sorts by title in ascending order, and then by price in descending order.
