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, ...
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
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.
