SQL Question

Invalid default value for 'create_date' timestamp field

I have the following sql create statement

mysql> CREATE TABLE IF NOT EXISTS `erp`.`je_menus` (
-> `id` INT(11) NOT NULL AUTO_INCREMENT ,
-> `name` VARCHAR(100) NOT NULL ,
-> `description` VARCHAR(255) NOT NULL ,
-> `live_start_date` DATETIME NULL DEFAULT NULL ,
-> `live_end_date` DATETIME NULL DEFAULT NULL ,
-> `notes` VARCHAR(255) NULL ,
-> `create_date` TIMESTAMP NOT NULL DEFAULT '0000-00-00 00:00:00',
-> `created_by` INT(11) NOT NULL ,
-> `update_date` TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP ,
-> `updated_by` INT(11) NOT NULL ,
-> `status` VARCHAR(45) NOT NULL ,
-> PRIMARY KEY (`id`) )
-> ENGINE = InnoDB;


giving following error

ERROR 1067 (42000): Invalid default value for 'create_date'


What is the error here?

Answer

That is because of server SQL Mode - NO_ZERO_DATE.

From the reference: NO_ZERO_DATE - In strict mode, don't allow '0000-00-00' as a valid date. You can still insert zero dates with the IGNORE option. When not in strict mode, the date is accepted but a warning is generated.
