escaping and quoting
Hello.
My dbmail server using postgresql produces a lot of warnings about '\\'
in strings. The particular string it is complaining about is escaped by
EscapeBytea, and included in single quotes (not E''). Is it all right to
set standard_compliant_strings to on?
Greetings,
Maarten Deprez
I got the following error when try to create a function to return an
integer and SETOF refcursor. I want to get refcursors back along with an
Out parameter in one function. There seems to be a conflict on return
type. How do I fix it? Thanks.
ERROR: function result type must be integer because of OUT parameters
CREATE OR REPLACE FUNCTION testrefcursor(IN uid integer, OUT tcount integer)
RETURNS SETOF refcursor AS
$BODY$
DECLARE
o_user refcursor;
o_name refcursor;
BEGIN
tcount := 100; -- add some logic to calculate tcount
OPEN o_user FOR SELECT * FROM usr_table where usr_id = uid;
RETURN NEXT o_user;
OPEN o_name FOR SELECT * FROM temp_table;
RETURN NEXT o_name;
END;
$BODY$
LANGUAGE 'plpgsql' VOLATILE
COST 100;

You can't. Perhaps it'd be enough to return the same integer value in
each row of the output?
