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;

sql distinct

#List unique values in the df['name'] column
df.name.unique()

sql server select rows by distinct column

SELECT a.*
FROM emails a
INNER JOIN
(SELECT email,
MIN(id) as id
FROM emails
GROUP BY email
) AS b
ON a.email = b.email
AND a.id = b.id;
