ResultSet
object.
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
level to support update, the cursor's SELECT
statement
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
SQL cursor used by a ResultSet
object.
The current row of a ResultSet
object
is also the current row of this SQL cursor.
Note: If positioned update is not supported, a
SQLException
is thrown.

public void refreshRow() throws SQLException
ResultSet
The 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.
