This is the code. However I kept getting this error 1064 - 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 ')' at line 7 Weirdly line 7 is the CREATE TABLE academicnews( line. Which does not contain ')' . CREATE TABLE academicnews( anewsID INT NOT NULL PRIMARY KEY AUTO_INCREMENT, title VARCHAR(50) NOT NULL, anewsContent TEXT NOT NULL, imagePath VARCHAR(200) NOT NULL, timeNews DATE NOT NULL, ); #Line 7 Get rid of the last comma. It is unnecessary and invalid. CREATE TABLE academicnews( anewsID INT NOT NULL
