code in docs gives me an error
Hi
I tried creating the function (from sec 19.3.1). But it gives me the
following error: "ERROR: type tablename does not exist".
Any ideas of what i might be doing wrong?
CREATE FUNCTION use_many_fields(tablename) RETURNS TEXT AS '
DECLARE
in_t ALIAS FOR $1;
BEGIN
RETURN in_t.f1 || in_t.f3 || in_t.f5 || in_t.f7;
END;
' LANGUAGE 'plpgsql';
Thanks,
--Hicham

You have to write the data type while defining the function parameters.
For example,
CREATE FUNCTION use_many_fields(varchar) RETURNS TEXT AS '
...and then declare it as you've done below:
DECLARE
in_t ALIAS FOR $1;

CREATE FUNCTION use_many_fields(tablename) RETURNS TEXT AS '
The example assumes you already created a table or composite type named
tablename.
