<div class="section"><p>The <a href="javadoc/com/ibm/as400/access/AS400JDBCRowSet.html#NAVBAR_TOP"> AS400JDBCRowSet</a> class represents a connected
|
||
|
|
rowset that encapsulates a JDBC result set. The methods on AS400JDBCRowSet
|
||
|
|
are very similar to those of the <a href="javadoc/com/ibm/as400/access/AS400JDBCResultSet.html#NAVBAR_TOP"> AS400JDBCResultSet</a>. The database connection
|
||
|
|
is maintained while in use.</p>
|
||
|
|
<p>You can use an instance of <a href="jdbcdatasource.htm#jdbcdatasource">AS400JDBCDataSource
|
||
|
|
or AS400JDBCConnectionPoolDataSource</a> to create the connection
|
||
|
|
to the database that you want to use to access the data for the AS400JDBCRowSet.</p>
|
||
|
|
</div>
|
||
|
|
<div class="section"><h4 class="sectiontitle">Examples</h4><p>The following examples show how you can
|
||
|
|
use the AS400JDBCRowSet class.</p>
|
||
|
|
<strong>Example: Creating, populating, and updating
|
||
|
|
an AS400JDBCRowSet object</strong> <pre> DriverManager.registerDriver(new AS400JDBCDriver());
|
||
|
|
// Establish connection by using a URL.
|
||
|
|
AS400JDBCRowSet rowset = new AS400JDBCRowSet("jdbc:as400://mySystem","myUser", "myPassword");

|
|
// Set the command used to populate the list.
|

|
|
rowset.setCommand("SELECT * FROM MYLIB.DATABASE");

// Populate the rowset.

|
