下面：

INSERT INTO Comments VALUES
('Mdbuzzer','Times Up', 'Best post I have seen in a while', '22:55pm', '22:00pm');

您正在将5个值插入到包含4列的表中。

INSERT INTO Comments(UsernameID, PostTitle, Comments, TimeofComments)
VALUES('Mdbuzzer','Times Up', 'Best post I have seen in a while', '22:55pm', '22:00pm');

列名或提供的值数与表不匹配
