Обсуждение: temp table creation

What's wrong with this function? The syntax is supposed to be right,
isn't it?

Create function UsaTablaTemporal()
RETURNS integer
AS '
    BEGIN

 SELECT p.apellidos, p.nombres, u.username
        INTO TEMP TABLE mitabla
        FROM persona p, usuario u
        WHERE p.idpersona = u.idusuario
          AND p.idpersona = 3278;

        RETURN 1;

    END;'
LANGUAGE 'plpgsql';

If I run:
select usatablatemporal();

I get the message:
ERROR:  parser: parse error at or near "temp"

Thanx

No, it isn't right, not for plpgsql.  SELECT INTO means something
different to plpgsql than it does in normal Postgres SQL.

In that case, how could I create a temporary table from plpgsql? (I don't
want to use select into table.......)

Thanx

CREATE [TEMP] TABLE foo AS SELECT ...

This is equivalent to SELECT INTO [TEMP] foo in regular SQL, and
does not change meaning in plpgsql.
