Hi All,
I am working on a query which in part is
CASE
WHEN extract(dow from tbl_detail.ship_by_date) = 0
THEN 'Sunday ' || tbl_detail.ship_by_date::text
WHEN extract(dow from tbl_detail.ship_by_date) = 1
THEN 'Monday ' || tbl_detail.ship_by_date::text
WHEN extract(dow from tbl_detail.ship_by_date) = 2
THEN 'Tuesday ' || tbl_detail.ship_by_date::text
WHEN extract(dow from tbl_detail.ship_by_date) = 3
THEN 'Wednesday ' || tbl_detail.ship_by_date::text
WHEN extract(dow from tbl_detail.ship_by_date) = 4
THEN 'Thursday ' || tbl_detail.ship_by_date::text
WHEN extract(dow from tbl_detail.ship_by_date) = 5
THEN 'Friday ' || tbl_detail.ship_by_date::text
WHEN extract(dow from tbl_detail.ship_by_date) = 6
THEN 'Saturday ' || tbl_detail.ship_by_date::text
END AS sort_by_string
Is there a better way to do this? The CASE seems inefficient and wordy
but perhaps not.
I was hoping for
day_name(tbl_detail.ship_by_date) || tbl_detail.ship_by_date::text AS
sort_by_string
but AFAIK day_name(date) or something like it is merely my fantasy. ;-)

Kind Regards,
