throws SQLException
ResultSetResultSet object.
If the row number is positive, the cursor moves to the given row number with respect to the beginning of the result set. The first row is row 1, the second is row 2, and so on.
If the given row number is negative, the cursor moves to
an absolute row position with respect to
the end of the result set. For example, calling the method
absolute(-1) positions the
cursor on the last row; calling the method absolute(-2)
moves the cursor to the next-to-last row, and so on.
An attempt to position the cursor beyond the first/last row in the result set leaves the cursor before the first row or after the last row.

as calling first(). Calling absolute(-1)
is the same as calling last().

In SQL, a result table is retrieved through a cursor that is
named. The current row of a result set can be updated or deleted
using a positioned update/delete statement that references the
cursor name. To insure that the cursor has the proper isolation

should be of the form SELECT FOR UPDATE. If
FOR UPDATE is omitted, the positioned updates may fail.
The JDBC API supports this SQL feature by providing the name of the

public void refreshRow()
throws SQLException
ResultSetThe refreshRow method provides a way for an
application to
explicitly tell the JDBC driver to refetch a row(s) from the
database. An application may want to call refreshRow when
caching or prefetching is being done by the JDBC driver to
fetch the latest value of a row from the database. The JDBC driver
may actually refresh multiple rows at once if the fetch size is
greater than one.
All values are refetched subject to the transaction isolation
level and cursor sensitivity. If refreshRow is called after
calling an updater method, but before calling
the method updateRow, then the
updates made to the row are lost. Calling the method
refreshRow frequently will likely slow performance.
