Get resultset from oracle stored procedure

Question

I\'m working on converting a stored procedure from SQL server to Oracle. This stored procedure provides a direct resultset. I mean that if you call the stored procedure in

Answer 1

My solution was to create a pipelined function. The advantages are that the query can be a single line:

• select * from table(yourfunction(param1, param2));
• You can join your results to other tables or filter or sort them as you please..
• the results appear as regular query results so you can easily manipulate them.

To define the function you would need to do something like the following:

  -- Declare the record columns
  TYPE your_record IS RECORD(
     my_col1 VARCHAR2(50), 
     my_col2 varchar2(4000)
  );
  TYPE your_results IS TABLE OF your_record;

  -- Declare the function
  function yourfunction(a_Param1 varchar2, a_Param2 varchar2)
  return your_results pipelined is
    rt          your_results;
  begin
    -- Your query to load the table type
    select s.col1,s.col2
    bulk collect into rt
    from your_table s
    where lower(s.col1) like lower('%'||a_Param1||'%');

    -- Stuff the results into the pipeline..
    if rt.count > 0 then 
      for i in rt.FIRST .. rt.LAST loop 
        pipe row (rt(i)); 
      end loop; 
    end if;

    -- Add more results as you please....
    return;
  end find;

And as mentioned above, all you would do to view your results is:

select * from table(yourfunction(param1, param2)) t order by t.my_col1;
