mysql disinct code example

Example 1: MySQL DISTINCT

When querying data from a table, you may get duplicate rows. In order to remove these duplicate rows, you use the DISTINCT clause in the SELECT statement.

Here is the syntax of the DISTINCT clause:

SELECT DISTINCT
    select_list
FROM
    table_name;
