    Sometimes we have the requirement to count how many unique values are in the table. We can do this by using "Distinct" and count().

    SELECT COUNT(DISTINCT column_name) FROM table_name;

    Example: Suppose you have a table user from which you want to count how many unique emails are in the table. You can do this by using the below command

    select count(distinct email_id) from user;

    in the above command Distinct will provide unique email ids and then will count them.

    Hope this will help you :)
