4,323 PointsDatabase Foundations - Add & Alter Table Column Change
I am stuck on Challenge question # 2 for Adding Columns Database Foundations.
Question: In one statement, in the movies table rename the year to release_year and change the type to the type of YEAR.
Code: ALTER TABLE movies CHANGE COLUMN year release_year, type type of the YEAR;
Response: Bummer! The column of 'release_year' of type YEAR is missing. SQL Error: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ' type type of the YEAR' at line 1

33,570 PointsJuan, you have an error in this SQL, you should change year_release to release_year.
Final solution is:
ALTER TABLE movies CHANGE COLUMN year release_year YEAR;

Thank you, I finally got it. YEAR is the key at the end of the code.

Hopefully, this helps you

7,894 PointsThere's no type type of the YEAR, you should use some sort of date type. I don't know exactly what the code is but in terms of mysql should it be something like:
ALTER TABLE movies CHANGE COLUMN year year_release date;
or so. I hope it helps, good luck!
