Guess your id column isn't set to autoincrement.

An example stolen from an other post

Code:
create table reservations (
   id BIGINT NOT NULL AUTO_INCREMENT,
   book_id VARCHAR(25),
   date_made DATE,
   member_id VARCHAR(20),
   remarks VARCHAR(255),
   limit_in_days INTEGER,
   primary key (id)
);
