SELECT show_name, show_address FROM show -----------------------------------------------
show_name show_address Dubbo 23 Wingewarra St, Dubbo Young 13 Cherry Lane, Young Castle Hill Showground Rd, Castle Hill Royal Easter PO Box 13, GPO Sydney Dubbo 17 Fitzroy St, Dubbo
Hi I'm trying to select Dubbo at 'Wingewarra St' and Castel Hill and list the number of days between them
Dubbo at 'Wingewarra St' was held on 05/ July / 1995 and Castle Hill was held on 04/ May/ 1996 and the result should be 304 days
and here is the show table:
SELECT *
FROM show --------------------------------------------------------- show_name show_held show_address Dubbo 1995-07-05 23 Wingewarra St, Dubbo Young 1995-09-13 13 Cherry Lane, Young Castle Hill 1996-05-04 Showground Rd, Castle Hill Royal Easter 1996-04-21 PO Box 13, GPO Sydney Dubbo 1996-07-01 17 Fitzroy St, Dubbo
and Here is the code that I wrote:
SELECT DATENAME (DAY, show_held.CastleHill) - DATENAME (DAY, show_held.Dubbo) AS number_of_days_between_show FROM show WHERE show.show_name = 'Dubbo' AND show.show_address LIKE 'Wingewarra St' ----------------------------------------------------- Msg 4104, Level 16, State 1, Line 24 The multi-part identifier "show_held.CastleHill" could not be bound. Msg 4104, Level 16, State 1, Line 24 The multi-part identifier "show_held.Dubbo" could not be bound.
I have no idea how to only select the day for Castle Hill and subtract the day of Dubbo that was held at Wingewarra St
Please help thank you
