Answer 1

You're right that passing new Date() would store the server time rather than the DB time.

To store the DB time you can set your timestamp to the DB system timestamp systimestamp then you could run a query to retrieve that row and its updated timestamp.

If you want to update the row and get the updated timestamp in a single execution then you could do the following using RETURNING INTO where TimestampUpdated is your column name:

Connection con = ...;
String sql = "UPDATE TableName SET  , TimestampUpdated = systimestamp RETURNING TimestampUpdated INTO ?";
CallableStatement statement = con.prepareCall(sql);
statement.registerOutParameter(1, Types.TIMESTAMP);

int updateCount = statement.executeUpdate();
Timestamp timestampUpdated  = statement.getInt(1);
System.out.println("Timestamp Updated = " + timestampUpdated);
