Fixing Invalid Default Value for TIMESTAMP Field in MySQL
When attempting to create a table with a TIMESTAMP field and specifying a default value of '0000-00-00 00:00:00', you may encounter the error "Invalid default value for 'create_date'." This is often due to a MySQL server SQL Mode setting.
Explanation
The NO_ZERO_DATE SQL Mode enforces strictness around the handling of zero dates. It prevents the insertion of '0000-00-00' as a valid date, considering it an invalid value.
Solution
To resolve the error, you can either:
Disable the NO_ZERO_DATE SQL Mode:
<code class="mysql">SET SQL_MODE='ONLY_FULL_GROUP_BY,STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ENGINE_SUBSTITUTION';</code>
Use the IGNORE option to allow the insertion of zero dates:
<code class="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' IGNORE, `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;</code>
Once you make these adjustments, you should be able to successfully create the table with the specified default value for the TIMESTAMP field.
