在表DBCON里维护一条记录，指向HANA数据库。con_ENV里填入HANA数据库的主机名和端口号。如vmXXXX:30015

然后使用ABAP代码创建一个新的table，插入三条entry进行，再读出来，最后删除table.

 Java实现类似： 

 public static void main(String[] args){ try {
                    Class.forName("com.sap.db.jdbc.Driver");
                    System.out.println("Create a connection...");
              con = (com.sap.db.jdbc.trace.Connection) DriverManager
                       .getConnection("jdbc:sap://:30015",// , "system", "此处填入登录密码");
                    cs = (com.sap.db.jdbc.trace.CallableStatement) con.prepareCall("call I042416_two_par(NULL, NULL)");
                    cs.execute(); int index = 0; do { int rowCount = 0;
                           com.sap.db.jdbc.trace.ResultSet rs = (com.sap.db.jdbc.trace.ResultSet)cs.getResultSet();
                           ResultSetMetaData metaData = rs.getMetaData(); int columnCount = metaData.getColumnCount(); while (rs != null && rs.next())
                           { for (int i = 1; i <= columnCount; i++)
                                 {
                                        System.out.print(rs.getString(i) + " "); if (i == columnCount)
                                        {
                                               System.out.println();
                                        }
                                 }
                                 System.out.println("Current Result Set Index:" + index + " Row Count: " + rowCount++);
                          
                           }
                           System.out.println("Result Set Index: " + index++);                          
                    } while(cs.getMoreResults());
             } 

console打印结果：数据能够成功通过JDBC从HANA数据库读取出来。
