Question 71/150
Which two statements are true about RowSet subinterfaces?
Correct Answer: A,C
Explanation/Reference:
Explanation:
A: a JdbcRowSet object can be one of the Beans that a tool makes available for composing an application.
Because a JdbcRowSet is a connected RowSet, that is, it continually maintains its connection to a
database using a JDBC technology-enabled driver, it also effectively makes the driver a JavaBeans
component.
C: The FilteredRowSet range criterion can be modified by applying a new Predicate object to the
FilteredRowSet instance at any time. This is possible if no additional references to the FilteredRowSet
object are detected. A new filter has an immediate effect on criterion enforcement within the
FilteredRowSet object, and all subsequent views and updates will be subject to similar enforcement.
