# Unique values

Let's assume we have the following table

**sales**

<div class="Lesson_content__j6FUx" id="bkmrk-%C2%A0-country-city-amoun"><figure class="table"><table><thead><tr><th> </th><th>country</th><th>city</th><th>amount</th></tr></thead><tbody><tr><td>1</td><td>Poland</td><td>Warsaw</td><td>13</td></tr><tr><td>2</td><td>Germany</td><td>Berlin</td><td>24</td></tr><tr><td>3</td><td>Poland</td><td>Katowice</td><td>56</td></tr></tbody></table>

</figure></div>And we would like to know all of the countries that the product was sold.

If we use the normal query we know: `SELECT country from sales` it will return `Poland Germany Poland`. This is not what we are looking for because Poland is repeated twice.

To solve it we can use the `DISTINCT` keyword:

```sql
SELECT DISTINCT country FROM sales
```
