SQL Query for Date field updation

Question

I want a query from u.. Hope u help me with a
solution soon..
My Q: I want to update a date field in Oracle
database. But the condition is that i shouldnt change
the hours, minutes & seconds of the date field.
generally , if we update the date field then it takes
the default values for hours, min's & sec's to
00:00:00.
EX : if we have a value 21-SEP-2002 04:54:44 in a date
field. I want to update it to 22-SEP-2002 04:54:44.
But it updates to 22-sep-2002 00:00:00 if we use
UPDATE command.

Answer 1

Use a PreparedStatement:
PreparedStatement ps = conn.prepareStatement("SELECT * FROM TEMP WHERE TDATE > ? AND TDATE < ?");
// note: month numbers start at 0, so 1 is february
GregorianCalendar c1 = new GregorianCalendar(2002, 1, 11, 11, 0);
GregorianCalendar c2 = new GregorianCalendar(2002, 1, 18, 22, 0);
Date d1 = c1.getTime();
Date d2 = c2.getTime();
java.sql.Timestamp sqlDate1 = new java.sql.Timestamp(d1.getTime());
java.sql.Timestamp sqlDate2 = new java.sql.Timestamp(d2.getTime());
ps.setTimestamp(1, sqlDate1);
ps.setTimestamp(2, sqlDate2);
ResultSet rs = ps.executeQuery();
// get results from the result setJesper
