Refresh this data column when creating and modifying records

`last_opt_ time`TIMESTAMP DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP COMMENT 'Last Operation time'

Set this field to the current time when you create it, but do not refresh it when you modify it later

`create_ time`TIMESTAMP DEFAULT CURRENT_TIMESTAMP COMMENT 'creation time'

Set this field to empty or fixed value when you create it, and refresh it later when you modify it.
