Devo dichiarare 12 variabili decimali, corrispondenti all'anno di ogni mese, con un cursore somma i valori a queste variabili, quindi in seguito aggiorno alcune informazioni di vendita.
Non so se sql server ha questa sintassi
Declare MonthsSale(1 to 12) as decimal(18,2)
Questo codice funziona bene. !
CREATE PROCEDURE [dbo].[proc_test]
AS
BEGIN
--SET NOCOUNT ON;
DECLARE @monthsales TABLE ( monthnr int, amount decimal(18,2) )
-- PUT YOUR OWN CODE HERE
-- THIS IS TEST CODE
-- 1 REPRESENTS JANUARY, ...
