System.out.println(rs.getRow());
rs.previous();
System.out.println(rs.getString(1));
rs.absolute(6);
System.out.println(rs.getString(1));

e.printStackTrace();
}
}
}
七、UpdateResultSet
import java.sql.*;
public class TestUpdataRs {
public static void main(String args[]){ try{
new oracle.jdbc.driver.OracleDriver();
String url="jdbc:oracle:thin:@192.168.0.1:1521:SXT";
Connection conn=DriverManager.getConnection(url,"scott","tiger");
Statement stmt=conn.createStatement(ResultSet.TYPE_SCROLL_INSENSITIVE,ResultSet.CONCUR_UPDATABLE); ResultSet rs=stmt.executeQuery("select * from emp2"); rs.next();
//更新一行数据
rs.updateString("ename","AAAA");
rs.updateRow(); //插入新行
rs.moveToInsertRow();
rs.updateInt(1, 9999);
rs.updateString("ename","AAAA");
rs.updateInt("mgr", 7839);
rs.updateDouble("sal", 99.99);
rs.insertRow();
//将光标移动到新建的行
rs.moveToCurrentRow(); //删除行
rs.absolute(5);
rs.deleteRow(); //取消更新
//rs.cancelRowUpdates(); }catch(SQLException e){
e.printStackTrace();
}
}
