the procedure for my requirement is like below.now my problem is how to call this procedure in my report.so that if i will send a parameter as letter_id then it should get my report stated above.
CREATE OR REPLACE PROCEDURE letter_text ( p_letter_id letter.letter_id%TYPE , p_letter_contents_out OUT SYS_REFCURSOR )
IS
BEGIN
OPEN p_letter_contents_out
FOR
SELECT letter_content
FROM letter
WHERE letter_id = p_letter_id
ORDER BY line_seq;
END letter_text;
which you might call with something like
SQL> var results refcursor
SQL> exec letter_text(103, :results)
PL/SQL procedure successfully completed.
SQL> print :results;
CONTENT

Answer 1

Thanks for ur suggestions.
i have 2 select statements.1st query is the main query for the report.so i used it at the time of report created with datablock.
now my 2nd query is
select letter_content
from ( select content_seq,
     content || case content_seq
when 2 then
' ' || lead(content) over (partition by letter_id order by content_seq)
end as letter_content
from exp_letter_contents
     where letter_id = 103)
where content_seq <> 3;
i had taken 2parameters 1 for the main query and 2nd is for the above query(parameter is letter_id).
now i have to write the above select statement in the report.
so i had taken a field object in the report and then i had written this code in before report trigger.
function letter_contentFormatTrigger return boolean is
begin
select letter_content
from ( select content_seq,
                    content ||
                    case content_seq when 2 then
                         ' ' || lead(content) over (partition by letter_id order by content_seq)
                    end as letter_content
          from exp_letter_contents
          where letter_id = 103)
where content_seq <> 3;
return (letter_content);
end;
when i tried to compile it.i got an error as follows :
error 103 at line6,column 5
encountered the symbol "CASE" when expecting one of the following:
(- + mod null <an identifier>
<a double-quoted delimited-identifier><a bind variable> avg...etc
so,where can i write this select statement.
i am using oracle reports6i
