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. ;-)
