All your have to do is create the field of type in order for the next part to work (this is because setting NOT NULL forces an automatic all zeros default).

CREATE TABLE Some Table ( id int unsigned NOT NULL AUTO_INCREMENT, status enum('broken','repaired') NOT NULL, from datetime NOT NULL, until datetime NOT NULL, brought_in timestamp, brought_by varchar(255) NOT NULL, repair_status enum('unpayed', 'payed') DEFAULT NULL, payed_when timestamp, delivered_when timestamp, primary key(id) ); . If you don't want this, you have to explicitly tell My SQL when you create the table.field in your insert query, it will be set to the current time stamp.Since all the queries in the application code specified the columns they were updating on insert, I was able to use this method to add created and modified time stamp fields to all the existing object tables in the database, without needing to modify any of the existing application code.This will use the SQL UPDATE command with the WHERE clause to update the selected data in the My SQL table tutorials_tbl.The following example will update the tutorial_title field for a record having the tutorial_id as 3.
