Example 2: 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;

Example 3: DISTINCT SQL

SELECT DISTINCT column1, column1, ..... FROM TABLE
/*DISTINCT WILL NOT SELECT THE SAME VALUES IN SAME COLUMN*/

Example 4: query DISTINCT

SELECT DISTINCT Column_name FROM table_name;
