Instead of "column", I guess you mean "value"?

If you want to store a date-value, use a date-datatype, not a character
based datatype.

> `elapsed` int default NULL,
> `src_ip` varchar(15) default NULL,
> `result_code` varchar(25) default NULL,
> `http_status` TINYINT default NULL,
> `bytes` int default NULL,
> `request` varchar(50) default NULL,
> `authname` varchar(10) default NULL,
