OUT parameters must be supplied by the caller and cannot be defaulted
(there is no place to put the OUTPUT to if you, the caller, does not
supply a variable).
You can:
variable msg varchar2(255)
exec spAddUser( 'pete', 'rose', :msg );
and if you want to see whats in msg after you are done, you can:
print msg
If you want to be able to call this WITH and WITHOUT a third parameter,
you could create an overloaded procedure in a package -- eg:
create or replace package sp
as
procedure addUser( x in varchar2, y in varchar2 );
procedure addUser( x in varchar2, y in varchar2, z out varchar2 );
end;
/
and in the package body, just implement the first adduser as a call to
the second -- supplying a dummy OUT variable for it. Then you could
call:
SQL> exec sp.AddUser( 'pete', 'rose' );
SQL> exec sp.AddUser( 'pete', 'rose', :msg );
