# SQL ORDER BY Keyword

The ORDER BY keyword is used to sort the result-set.

## The ORDER BY Keyword

The ORDER BY keyword is used to sort the result-set by a specified column.

The ORDER BY keyword sort the records in ascending order by default.

If you want to sort the records in a descending order, you can use the DESC keyword.

### SQL ORDER BY Syntax

    SELECT column_name(s)
    FROM table_name
    ORDER BY column_name(s) ASC|DESC

## ORDER BY Example

The "Persons" table:

P_Id | LastName | FirstName | Address | City
--- | --- | --- | --- | ---
1 | Hansen | Ola | Timoteivn 10 | Sandnes
2 | Svendson | Tove | Borgvn 23 | Sandnes
3 | Pettersen | Kari | Storgt 20 | Stavanger
4 | Nilsen | Tom | Vingvn 23 | Stavanger

Now we want to select all the persons from the table above, however, we want to sort the persons by their last name.

We use the following SELECT statement:

    SELECT * FROM Persons
    ORDER BY LastName

The result-set will look like this:

P_Id | LastName | FirstName | Address | City
--- | --- | --- | --- | ---
1 | Hansen | Ola | Timoteivn 10 | Sandnes
4 | Nilsen | Tom | Vingvn 23 | Stavanger
3 | Pettersen | Kari | Storgt 20 | Stavanger
2 | Svendson | Tove | Borgvn 23 | Sandnes

## ORDER BY DESC Example

Now we want to select all the persons from the table above, however, we want to sort the persons descending by their last name.

We use the following SELECT statement:

    SELECT * FROM Persons
    ORDER BY LastName DESC

The result-set will look like this:

P_Id | LastName | FirstName | Address | City
--- | --- | --- | --- | ---
2 | Svendson | Tove | Borgvn 23 | Sandnes
3 | Pettersen | Kari | Storgt 20 | Stavanger
4 | Nilsen | Tom | Vingvn 23 | Stavanger
1 | Hansen | Ola | Timoteivn 10 | Sandnes
