SQL Select Distinct

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.

Syntax

SELECT DISTINCT column1, column2, ...
FROM table_name;

SELECT DISTINCT Example

The following SQL statement selects only the DISTINCT values from the "Country" column in the "Customers" table:

SELECT DISTINCT Country FROM Customers;

The following SQL statement counts and returns the number of different (distinct) countries in the "Customers" table:

SELECT COUNT(DISTINCT Country) FROM Customers;
