explicit_defaults_for_timestamp这个值，默认设置ON比较好，但是无论设置OFF还是ON，关于有TIMESTAMP的CREATE TABLE t (x int(11) DEFAULT NULL,y timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP,z timestamp NULL DEFAULT NULL,a timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP
) ENGINE=InnoDB DEFAULT CHARSET=utf8
例子罗列了三种TIMESTAMP的状态，必须要确定这个表相关列需要的正确状态。
explicit_defaults_for_timestamp再议
