The SQL SELECT DISTINCT Statement

The SELECT DISTINCT statement is used to return only distinct (different) values.

Inside a table, a column often contains many duplicate values; and sometimes you only want to list the different (distinct) values.

SELECT DISTINCT Syntax

SELECT DISTINCT column1, column2, ...

FROM table_name; 

SELECT Example Without DISTINCT

The following SQL statement selects ALL (including the duplicates) values from the "Country" column in the "Customers" table:

Example

SELECT Country FROM Customers;
