timestamp on update

[Destramic]

 hey guys here is my table below:

CREATE TABLE IF NOT EXISTS `sessions` (
  `id` varchar(62) NOT NULL,
  `data` text NOT NULL,
  
`lifetime` int(10) NOT NULL,
  `created` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP,
  
`modified` timestamp NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP
) 
ENGINE=InnoDB

my problem is when i use  a replace into query

REPLACE INTO sessions (id, data, lifetime) VALUES ('1234', 'data here', '360')

whats happening is when replacing a row the created column is  always gets updated with the current timestamp...

 

which is because im using the replace into function....is there a way when existing the replace into, which updates a row for it not to update the created column?

 

thanks you

You use REPLACE for updating values within existing rows

 

If are inserting a record but don't want duplicate records use INSERT IGNORE

Replace will DELETE then INSERT an new record if there is record there already with same key.

 

Try using INSERT...ON DUPLICATE KEY UPDATE instead

thanks for you post guys

INSERT INTO sessions (id, data, lifetime) 
VALUES (1, 'done it', '260') 
ON DUPLICATE KEY 
UPDATE data = 'done it', lifetime = '260

worked like a dream
