date-parsing

问题 How to convert the following into date for insertion/update into a TIMESTAMP or DATE field in MySQL? \'15-Dec-09\' DATE_FORMAT() is used to format date, but not the other way around. 回答1: You may want to use the STR_TO_DATE() function. It's the inverse of the DATE_FORMAT() function. 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

问题 I checked the SimpleDateFormat javadoc, but I am not able to find a way to parse the ordinal indicator in a date format like this: Feb 13th 2015 9:00AM I tried \"MMM dd yyyy hh:mma\" , but the days have to be in number for it to be correct? Is it possible to parse the \"13th\" date using a SimpleDateFormat without having to truncate the string? 回答1: Java's SimpleDateFormat doesn't support an ordinal suffix, but the ordinal suffix is just eye candy - it is redundant and can easily be removed
