# Unique values Let's assume we have the following table **sales**
countrycityamount
1PolandWarsaw13
2GermanyBerlin24
3PolandKatowice56
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 ```
