1) The easiest way to do the update would be to use your DBMSs
built-in date functionality. If date_Return is a date datatype
in your DBMS then there should be a function to add a number of
days to it. For example, in Sybase, you could write your UPDATE
statement as:
"update resources set date_Return = DateAdd(day, 7, date_Return)".
2) If, by UK date, you mean day-month-year, you can format the date
using the java.text.SimpleDateFormat.
