How to Execute a SP with onlly one OUTPUT parameter.

Question

I have SP as:-
CREATE OR REPLACE PROCEDURE spt_remove_duplicates_pr (outbuffer OUT VARCHAR2)
IS
buff VARCHAR2(32000) := ' ';
BEGIN
buff := ' Hi From Stored Proc' ;
outbuffer : = buff;
END;
How can I execute it and get the output result ?
I have tried as
declare
buff VARCHAR2(32000) := '';
begin
select (exec spt_remove_duplicates_pr(buff)) into buff from dual;
DBMS_OUTPUT.put_line (buff);
end;
END;
but getting errors as : -
ORA-06550 line string, column string:string
Cause: A PL/SQL compilation error has occurred. The numbers given for line and column are the location in the PL/SQL block where the error occurred.
Please help.

Answer 1

Probably I was being hasty in my assumptions. If you really need a procedure, use it like the following.
SQL> l
1 CREATE OR REPLACE PROCEDURE spt_remove_duplicates_pr (outbuffer OUT V
2 IS
3 buff VARCHAR2(32000) := ' ';
4 BEGIN
5 buff := ' Hi From Stored Proc' ;
6 outbuffer : = buff;
7
8* END;
SQL> /
Warning: Procedure created with compilation errors.
SQL> show errors

6 end;

Just a side note, you got an error in line 6 of your procedure. In assignment operator :=
there must not be any symbols (including spaces) between : and =
