Combining cities and states using +

In this lesson, you learned how to combine columns into one.

The clients table has one column, city, to store the cities where the clients live, and another column, state, to store the state of the city.

| client_id | client_name | client_surname | city      | state    |
|-----------|-------------|----------------|-----------|----------|
| 1         | Miriam      | Antona         | Las Vegas | Nevada   |
| 2         | Astrid      | Harper         | Chicago   | Illinois |
| 3         | David       | Madden         | Phoenix   | Arizona  |
| ...       | ...         | ...            | ...       | ...      |

You need to combine city and state columns into one, to have the following format: 'Las Vegas, Nevada'.

You will use + operator to do it.

  • Concatenate the names of the cities with the states using the + operator without worrying about NULL values.
