I'm trying to write any function which returns chars or few columns from
table but it dosn't work.
This my sample function and it dosn't work meybe sombady can help me and
tell what I'm doing wrong.
CREATE FUNCTION one(int4) RETURNS int4 AS 'select id from s_url where
id_url=$1;' LANGUAGE 'sql'
id is int4 and primary key
id is int4
and second question:
did I in good way sending parameters to the function.
Maybe sombady have few sample function which could send me, or same manual
files(but other than that which are in pgman).
Thanks
Robert
