It is possible to invoke the procedure to output a data table from a table definition directly from a SQL client. This is useful primarily for debugging and for developers.

Running in SQL (by platform)

PostgreSQL 

1. Load the updated script

   \i /path/to/rpdo_refcursor.sql

2. Run the procedure

   BEGIN;
    -- 'cur' is the default cursor name
    CALL usp_rpdo2(
      p_table_instance_id  := 322,
      p_result_instance_id := NULL,
      p_min_row            := NULL,
      p_max_row            := NULL
    );
    -- retrieve all rows from the cursor
    FETCH ALL FROM cur;
   COMMIT;

Notes:

• Because usp_rpdo2 now uses an INOUT cur REFCURSOR DEFAULT 'cur', you don’t need to supply a cursor name.
• The FETCH ALL FROM cur returns every column of your pivoted result set.

Oracle

1. Load the script

   @/path/to/your_oracle_script.sql

2. Bind and call

   VAR rc REFCURSOR;
   EXEC usp_rpdo2(
    p_table_instance_id  => 322,
    p_result_instance_id => NULL,
    p_min_row            => NULL,
    p_max_row            => NULL,
    p_refcursor          => :rc
   );

3. View the cursor

   PRINT rc;

Notes:

• VAR rc REFCURSOR declares a bind variable in SQL*Plus/SQL Developer.
• PRINT rc streams the full result set into your grid or console.

If your SQL client doesn't support PRINT, the following code will output the cursor as a nice table:

DECLARE
  rc          SYS_REFCURSOR;
  cur         INTEGER;
  col_cnt     INTEGER;
  desc_tab    DBMS_SQL.DESC_TAB;
  v_val       VARCHAR2(4000);
  header_line VARCHAR2(32767);
  row_line    VARCHAR2(32767);
BEGIN
  -- 1) Call the proc
  usp_rpdo2(
    p_table_instance_id  => 1,
    p_result_instance_id => NULL,
    p_min_row            => NULL,
    p_max_row            => NULL,
    p_refcursor          => rc
  );

  -- 2) Convert to DBMS_SQL cursor
  cur := DBMS_SQL.TO_CURSOR_NUMBER(rc);

  -- 3) Describe & define columns
  DBMS_SQL.DESCRIBE_COLUMNS(cur, col_cnt, desc_tab);
  FOR i IN 1..col_cnt LOOP
    DBMS_SQL.DEFINE_COLUMN(cur, i, v_val, desc_tab(i).col_max_len);
  END LOOP;

  -- 4) Print header row as CSV
  header_line := NULL;
  FOR i IN 1..col_cnt LOOP
    header_line := header_line
      || CASE WHEN i>1 THEN ',' ELSE '' END
      || '"' || desc_tab(i).col_name || '"';
  END LOOP;
  DBMS_OUTPUT.PUT_LINE(header_line);

  -- 5) Fetch & print each row as CSV
  WHILE DBMS_SQL.FETCH_ROWS(cur) > 0 LOOP
    row_line := NULL;
    FOR i IN 1..col_cnt LOOP
      DBMS_SQL.COLUMN_VALUE(cur, i, v_val);
      row_line := row_line
        || CASE WHEN i>1 THEN ',' ELSE '' END
        || '"' || REPLACE(NVL(v_val,''),'"','""') || '"';
    END LOOP;
    DBMS_OUTPUT.PUT_LINE(row_line);
  END LOOP;

  -- 6) Clean up
  DBMS_SQL.CLOSE_CURSOR(cur);
END;

...

SQL Server 

1. Load the script

   :r C:\path\to\rpdo2.sql

2. Execute the procedure

   EXEC dbo.usp_rpdo2
    @TABLE_INSTANCE_ID  = 322,
    @RESULT_INSTANCE_ID = NULL,
    @MIN_ROW            = NULL,
    @MAX_ROW            = NULL;

3. View results

   • By default, the proc’s dynamic SQL writes its pivoted output directly to your result grid.

   • Optionally, to capture it in a temp table for further querying:

     CREATE TABLE #my_results (... define columns ...);
     INSERT INTO #my_results
     EXEC dbo.usp_rpdo2
     @TABLE_INSTANCE_ID  = 322,
     @RESULT_INSTANCE_ID = NULL,
     @MIN_ROW            = NULL,
     @MAX_ROW            = NULL;
     
     SELECT * FROM #my_results;
     DROP TABLE #my_results;

Notes:

• Local # tables created inside a proc aren’t accessible afterward, so if you need post‑proc querying, use a global temp table (##…) or insert the output as shown above.
• In SSMS, you’ll also see the rows immediately in the grid after EXEC.
