I have added a column name month_added, I run the query to extract the month from the date_added column in my table but I get an error:

ERROR: column "date_added" does not exist
LINE 1: SELECT date_added, DATENAME (MONTH, date_added) ^
SQL state: 42703
Character: 8

ALTER TABLE movies
ADD month_added VARCHAR (50);

UPDATE movies
SET month_added = MONTH(date_added);

I have also tried the EXTRACT date function
