MySQL - Create table with a specific TIMESTAMP format

Question

Is there any way to create a table with a specific TIMESTAMP format (HH:mm:00) where I need to fix sec to 00.

CREATE TABLE `published` (
  `time_pub` timestamp() NULL DEFAULT NULL,
) ENGINE=InnoDB DEFAULT CHARSET=latin1;

Answer 1

You can't change the way the timestamp is stored. Only the way it is presented in your select statements.

Another solution would be to store the data in a hour and minute column having an integer data type.

Answer 2

尽管在创建表时无法指定时间格式，但是当将数据插入数据库时​​，可以使用MySQL date_format函数将第二部分固定为00。

insert into TABLE_NAME values (date_format(now(), '%H:%m:00'));
