Re: how to use variables in postgresql

[Christoph Della Valle <christoph(dot)dellavalle(at)goetheanum(dot)ch>]

and use DECLARE ;-)

I HAVE A PROBLEM REGARDING DECLARATION/ INITIALISATION OF VARIABLES IN
POSTGRESQL FUNCTIONS AND PROCEDURES. MY CODE PRESENTLY LOOKS LIKE
CREATE FUNCTION ins_into_std_values() RETURNS void AS
$BODY$
DECLARE
 myflag CHAR(1) :='y';
BEGIN
 ...
END
$BODY$
LANGUAGE 'plpgsql' VOLATILE;
