Обсуждение: Returning Recordsets from Stored-procs

Is there anyway to return a recordset from a Stored Procedure in Postgres so that it can be used as a type of view or
select?
I know that you can do this in Interbase or MS-SQL.

I have seen that you can return a complete record but that's not really the same thing.

In short:-   No, there isn't.

More detail:-   PostgreSQL does not have stored procedures as such, it has user defined functions. The difference being
thata stored
 
procedure returns both a scalar value (the result), and optionally, one or more sets. (your recordset)
   Functions on the other hand, only return a scalar value. This has been slightly extended in PostgreSQL so that a
listof
 
values can be returned, but these have to be of the same type, and so are not a general replacement for a set.

Whilst this is an unfortunate position at the moment, it has been my experience that it does not cause insurmountable
problems.
(Some short term headaches - yes. ;-)

After learning this as a fact you have short term headaches but before
you have continuos headache while trying to port a database.
I think I'm not the only one who would be really, really happy if
*real* stored procedures would be high on top of the todo list.

(In fact this is the *only* thing I'm currently really missing in
PostgreSQL.)

Kind regards
        Andreas.
