Hi folks
I've got 2 tables,
availabiliy
~~~~~~~
stdate date
edate date
workdays integer
comments text
example record
2007-03-01 2007-03-07 5 Please can I have alternate days
roster
~~~~
rdate date
rdiag varchar(10)
example
2007-03-01 B12
2007-03-03 B11
2006-03-05 B12
2007-03-07 B13
What would be the best way to create a view to list every date within a range
giving either rostered, available but not rostered, and not available?
I've read through the docs and created a function (below) to return every date
within a range, but I can't get my head round converting that to a query.
Although I'm doing this as a learning exercise, it will be used in a web site
I'm developing so comments on speed and efficiency would also be welcome.

create or replace function date_range(fdate date,tdate date) returns setof
date
AS $PROC$
DECLARE wdate date;
BEGIN return next fdate; wdate:=fdate+1; while wdate <= tdate LOOP return next wdate; wdate:=wdate+1; end LOOP;
return;
END;
$PROC$ LANGUAGE plpgsql;
