Java Reference
In-Depth Information
The first thing you will notice is that the entire example centers on the methods of the
RowSet
. If you
are working with a
ResultSet
, you will have to create and work with the following objects:
java.sql.Connection
java.sql.Statement
java.sql.ResultSet
When using a
RowSet
such as the one in
Listing 18-1
, set the required properties of the
RowSet
itself.
Then use the
RowSet.execute()
method to execute the SQL command. The
JdbcRowSet
is
implemented as a wrapper around a
ResultSet
object that makes it possible to use the ResultSet as a
JavaBeans component. Because a
JdbcRowSet
is a connected
RowSet
, continually maintaining its
connection to the database using a JDBC driver, it effectively makes the driver a JavaBeans component.
Listing 18-1: Using a RowSet
package JavaDatabaseBible.ch18;
import java.sql.*;
import com.inet.tds.JDBCRowSet;
public class JDBCRowSetExample{
public static void main(String[] argv){
String url = "jdbc:inetdae7:localhost:1433?database=LEDES";
String login = "jod";
String password = "jod";
try {
Class.forName("com.inet.tds.TdsDriver").newInstance();
JDBCRowSet rowSet = new JDBCRowSet();
//set url,login and password;
rowSet.setUrl( url );
rowSet.setUsername( login );
rowSet.setPassword( password );
//get the driver version
DatabaseMetaData dbmd = rowSet.getConnection().getMetaData();
System.out.println("Driver Name:\t" + dbmd.getDriverName());
System.out.println("Driver Version:\t" + dbmd.getDriverVersion());
//set the sql command
rowSet.setCommand("SELECT ID,FName,LName,EMail FROM CONTACTS");
//execute the command
