Hi There,

How to convert yyyy-mm-dd hh:mm:ss.sss to only yyyy as a String.

i.e: my value in DB of type datetime, 2009-11-04 00:00:00.0 to 2009 as a String.

Thanks.

Simplest would be
String d = String.format("%tY", resultSet.getDate(someCol));

@CEHJ:

what if the date is not coming from resultSet, but just as String?

Well you could do a substring then ;)

I do it this way:

select to_char(date_col_name,'YYYY') from table

  String dateString = resultSet.getString(1)

Works with Orcale, don't know if it works with other databases

If it comes just as String, you can use SimpleDateFormat

SimpleDateFormat f = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss.SSS");
SimpleDateFormat f1 = new SimpleDateFormat("yyyy");

java.util.Date dd = f.parse(dateString, new ParsePosition(0));

String newString = f1.format(dd);

Substring is of course simpler :)

use of substring is error prone, best to use SimpleDateFormat as for_yan suggested above to parse the date string, then format it as a string as required
