> STR_TO_DATE(str,format) This is the inverse of the DATE_FORMAT() function. It
> takes a string str and a format string format. STR_TO_DATE() returns a
> DATETIME value if the format string contains both date and time parts, or a
> DATE or TIME value if the string contains only date or time parts. If the
> date, time, or datetime value extracted from str is illegal, STR_TO_DATE()
> returns NULL and produces a warning.
