Error Code 1062 Duplicate Primary Key

[Karen Ledin]

Hi! I have been working on this for awhile. This is the table:

CREATE TABLE pres_term
(
pres_id INT UNSIGNED NOT NULL AUTO_INCREMENT,
term_start_date DATETIME(6),
term_end_date DATETIME(6),
number_of_elections_won INT(10),
reason_for_leaving_office CHAR(25),
PRIMARY KEY (pres_id)
) ;

This is the original script to insert data: (just the first 3 or so rows - there are quite a few)

Insert into pres_term values ( 1, '1789-07-01', '1797-03-04', 2,
'Did not seek re-election', NUll);
Insert into pres_term values ( 2, '1797-03-04', '1801-03-04', 1,
'Lost reelection', null);
Insert into pres_term values ( 3, '1801-03-04', '1809-03-04', 2,
'Did not seek reelection', null);

With the above I get: Error Code: 1136. Column count doesn't match value count at row 1

I remove Null and that seemed to work for that Error but then I get Error Code: 1062. Duplicate entry '1' for key 'PRIMARY'

I have tried a number of things to fix it and I keep getting the same thing. What am I doing wrong? Thank you.
