Unable to insert multiple records to a row

[osherdo]

I am trying to insert multiple rows to a column in mysql like this:

INSERT INTO `sportsapp`.`exercises` (`id`, `image_path`, `name`, `category`) VALUES ('3', 'exercises/biceps/barbell_curls_lying_against_an_incline.jpg', 'Barbell Curls Lying Against An Incline', 'Biceps'),
('4','exercises/biceps/cable_hammer_curls_-_rope_attachment','Cable hammer Curls - Rope Attachment','Biceps');

I am getting an error in return:

 

 

#1062 - Duplicate entry '3' for key 'PRIMARY'

 

I tried to google and understand what's the reason for it, but I dont get it. I do have already a primary key, and I don't know why it generates another primary key,

 

Could you please try to help with this?

ignore it, I have mistakenly tried to insert to the same id that already existed, and it thrown an error.

Is the "id" column set to auto increment? If so, you could leave it out of the query.

INSERT INTO `sportsapp`.`exercises` (`image_path`, `name`, `category`) VALUES 
('exercises/biceps/barbell_curls_lying_against_an_incline.jpg', 'Barbell Curls Lying Against An Incline', 'Biceps'), 
('exercises/biceps/cable_hammer_curls_-_rope_attachment', 'Cable hammer Curls - Rope Attachment', 'Biceps');
