date

问题 I am using a generic method to loop through and convert a ResultSet to a String array. I am wondering why does the Date column in Oracle db value come print out as 2015-01-09 00:00:00.0 while the date in the database shows 2015-01-09 ?

(I've considered building a table listing the dates I'm willing to accept, and use that in a sub-select, but that seems awfully inelegant.) Cheers,

The list of results in this case is a list of EventResults: public class EventResult :
