The RowSet
interface provides a set of JavaBeans properties that allow a RowSet
instance to be configured to connect to a JDBC data source and read
some data from the data source. A group of setter methods (setInt
,
setBytes
, setString
, and so on)
provide a way to pass input parameters to a rowset's command property.
This command is the SQL query the rowset uses when it gets its data from
a relational database, which is generally the case.
The RowSet
interface supports JavaBeans events, allowing other components in an
application to be notified when an event occurs on a rowset,
such as a change in its value.
The RowSet
interface is unique in that it is intended to be
implemented using the rest of the JDBC API. In other words, a
RowSet
implementation is a layer of software that executes "on top"
of a JDBC driver. Implementations of the RowSet
interface can
be provided by anyone, including JDBC driver vendors who want to
provide a RowSet
implementation as part of their JDBC products.
A RowSet
object may make a connection with a data source and
maintain that connection throughout its life cycle, in which case it is
called a connected rowset. A rowset may also make a connection with
a data source, get data from it, and then close the connection. Such a rowset
is called a disconnected rowset. A disconnected rowset may make
changes to its data while it is disconnected and then send the changes back
to the original source of the data, but it must reestablish a connection to do so.
A disconnected rowset may have a reader (a RowSetReader
object)
and a writer (a RowSetWriter
object) associated with it.
The reader may be implemented in many different ways to populate a rowset
with data, including getting data from a non-relational data source. The
writer can also be implemented in many different ways to propagate changes
made to the rowset's data back to the underlying data source.
Rowsets are easy to use. The RowSet
interface extends the standard
java.sql.ResultSet
interface. The RowSetMetaData
interface extends the java.sql.ResultSetMetaData
interface.
Thus, developers familiar
with the JDBC API will have to learn a minimal number of new APIs to
use rowsets. In addition, third-party software tools that work with
JDBC ResultSet
objects will also easily be made to work with rowsets.
