Populating 2dimentional array from database table

Question

Hi,
I have created two dimentional array
TYPE type_DIR IS TABLE OF site_direction.site_direction_id%TYPE INDEX BY    BINARY_INTEGER;
TYPE type_DIR_LAN IS TABLE OF type_DIR INDEX BY BINARY_INTEGER;
var_DIR_LAN type_DIR_LAN;I have to populate data into this from a relational database tables "site_direction" and "site_lanes".
I'm using cursors like below.
  CURSOR lane_numbers(c_site_id NUMBER, c_direction_id NUMBER) IS
       SELECT site_lane_id
      FROM site_lanes
         JOIN report_parameters
           ON site_lane_id = report_parameter_value
        WHERE site_lanes.site_id           = c_site_id
          AND site_lanes.site_direction_id = c_direction_id
          AND report_parameters.report_parameter_id  = in_report_parameter_id
          AND report_parameters.report_parameter_group = 'LANE'
       AND report_parameters.report_parameter_name  = 'LANE'
  ORDER BY site_lane_id;
     CURSOR direction_id(c_site_id NUMBER) IS
     SELECT site_direction_id
       FROM site_direction
       JOIN sites
         ON site_direction.site_id = c_site_id
       JOIN report_parameters
         ON site_direction.site_id = report_parameter_value
      WHERE report_parameters.report_parameter_id  = in_report_parameter_id
           AND report_parameters.report_parameter_group = 'SITE'
        AND report_parameters.report_parameter_name  = 'SITE_ID'
   ORDER BY site_direction_id;  How could I do that?
Once I got populated two dimentional array with value, how could I return that values?
Do I need one more 2 dimentional array to return or could I use sys_refcursor?
Thanks.

Return the values to what? Using what version of what software?
Ideally you are using those cursors, though I can't imagine why they are necessary, to BULK COLLECT into the array. If so then just pass the array as a parameter.
If passing back to an external program like JAVA or .NET then a REF CURSOR would be appropriate.
