Обсуждение: Problem with function invocation

 Hello.

 When I create next function:

     create function pilpot() returns integer as '
        declare
            foo integer;
        begin
            foo = insert into aviso(user) values(1);
            return foo;
        end;
    ' language 'plpgsql';

 And try to invoque with:

     # select pilpot();

 I get next error:

     ERROR: parser: parse error at or near "("

 Where is the problem with this?

 Thanks a lot.

                                 David

INSERT doesn't return a value AFAIK ...

What exactly are you trying to return from the function?
Removing the foo declaration and foo = from the insert line
(and double quoting the reserved word user) on 7.1 makes
the function work for me (I just returned 1).

don't assignments have to be pascal-style, with a colon?

    var := expression + some / value ;

and then, doesn't the rhs (right-hand side) have to return a
value? i don't think insert does return anything pertinent
(except in psql where you can see the oid and the 'record count'
[or is it more like an 'activity count'?]).  <== do i get a prize
for the most-consecutive punctuation within an english-text
paragraph? :)
