Answer 1

I think you are looking for UPDATE and not insert?

UPDATE `users`
SET `username` = 'Jack', `password` = '123'
WHERE `id` = 1

Answer 2

INSERT INTO users (id,username, password) 
VALUES ('1','Jack','123')
ON DUPLICATE KEY UPDATE username='Jack',password='123'

This will work only if the id field is unique/pk (not composite PK though) Also, this will insert if no id of value 1 is found and update otherwise the record with id 1 if it does exists.

Answer 3

Try this:

Update users
Set username = 'Jack', password='123'
Where ID = '1'

Or if you're actually trying to insert:

Insert Into users (id, username, password) VALUES ('1', 'Jack','123');

Answer 4

In an insert statement you wouldn't have an existing row to do a where claues on? You are inserting a new row, did you mean to do an update statment?

update users set username='JACK' and password='123' WHERE id='1';
