Обсуждение: Function return type does not match

Hi I modified my function to:

CREATE FUNCTION buscablista (character varying, character varying) RETURNS
SETOF cabezalista
    AS '

select * from cabezalista where idlista like CAST($1 AS CHAR(20)) and
idlibro like CAST($2 AS CHAR(6));

' LANGUAGE sql;

But when called it gives me the error:

ERROR:  Query-specified return tuple and actual function return tuple do not
match
ERROR:  Query-specified return tuple and actual function return tuple do not
match

As i see it, the return types are the same (cabezalista) whic is a table in
my database... I think something went wrong when i dropped and re created
the table in order to add a column and do some other minor changes (like
changing char(6) to char (7) in some columns)

Thanks a lot

I guess that you are calling the function like is a function:

select buscablista('foo', 'bar');

the function is a Table Function so :

select * from buscablista('foo', 'bar');

Because of how functions caches database information, dropping the
table and/or columns results in an error.

You just need to re-create the function in question and all should be
fine.

Thanks heat for your help but I did that and it still ives me the same
error... I restarted the srver and the computer and nothing seems to work...

Do you know any other reason for this to happen?

Thanks a lot

Generally, when asking for assistance, you'll want to provide more
details. In this instance, for example, you should provide:

1) the version of Postgres you're working with. (You can type "select
version();" to find out if you're not sure.)
2) a copy of the entire function in question (or relevant parts of it's
a lengthy function and only one part of it is causing problems
3) the exact SQL statement that triggered the error or unexpected
result (e.g. "select my_function() from my_table;")
4) the resulting error message or unexpected results. (If it's an
error, you should copy and paste the entire error message.)

 From what you've provided in your previous email, I have no idea what
is causing the error, but with a little more detail I'm sure someone
will be able to help you.
