Thread: Question about passing User defined types to functions

is there a example on how to pass user defined types into
a function??

What I am looking for is something of this nature.

CREATE TYPE dumby_type AS (dumby_id int4, dumby_name text);

create function kick_dumby(dumby dumby_type) returns INTEGER AS '
DECLARE somenumber integer;
BEGIN return 1;
END;
' language 'plpgsql';


Is there some way of doing this, because the above doesn't work.

After having a look into the documentation on CREATE TYPE
I would say the statement looks very wrong. But I haven't done
any user defined type so far, so I can't be of any help in this case.
The CREATE FUNCTION statement is not considered to accept
parameter names within the parameter list.
So use
create function kick_dumby(dumby_type) returns INTEGER AS '
DECLAREdumby ALIAS FOR $1;
...

Should be

create function kick_dumby(dumby_type) returns INTEGER AS '...
