Replace Table - Update Field, Move Records to another table MySQL

Create a table

CREATE TABLE IF NOT EXISTS `users` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `name` varchar(200) DEFAULT NULL,
  `image` varchar(255) DEFAULT NULL,
  `company` varchar(150) DEFAULT NULL,
  `created` datetime DEFAULT NULL,
  `modified` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB  DEFAULT CHARSET=latin1 AUTO_INCREMENT=1 ;

search for 'arun' in 'arun kumar' and replace with 'pardeep'

select replace('arun kumar','arun','pardeep') 

It will print "pardeep kumar"

search for 'php' in company field and replace with 'php-tutorial-php'

UPDATE users SET company = REPLACE(company, 'php', 'php-tutorial-php');

Replace a table

REPLACE INTO T SELECT * FROM T;

Note:
If you run a replace on existing keys on table "users", and table "profile" references "users" with a forgein key constraint ON DELETE CASCADE,
If you replace table "users"
then table "users" will be updated - but table "profile" will be emptied due to the DELETE before INSERT.

mysql insert syntax - Add records from another table - Copy Table from one table to another

Create a table

CREATE TABLE IF NOT EXISTS `users` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `name` varchar(200) DEFAULT NULL,
  `image` varchar(255) DEFAULT NULL,
  `company` varchar(150) DEFAULT NULL,
  `created` datetime DEFAULT NULL,
  `modified` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB  DEFAULT CHARSET=latin1 AUTO_INCREMENT=1 ;

Insert record - Way 1

insert into `users` set name='php tutorial'

Insert record - Way 2

INSERT INTO `users` (`id`, `name`, `image`, `company`, `created`, `modified`) VALUES (NULL, 'arun', NULL, 'php-tutorial', NULL, CURRENT_TIMESTAMP);

Add multiple records

INSERT INTO `mysql_certification`.`users` (`id`, `name`, `image`, `company`, `created`, `modified`) VALUES (NULL, 'arun', NULL, 'php-tutorial', NULL, CURRENT_TIMESTAMP), (NULL, 'arun', NULL, 'php-tutorial', NULL, CURRENT_TIMESTAMP);

Copying rows from one table to another

INSERT INTO `users`  (name, company) select name, company from users where id<5
