私はこの手順を持っていますが、出力パラメーター @bit を設定している 2 つの if なしで、完全に機能する場合。proc p3を実行しようとすると、次のエラーが発生します
Must declare the scalar variable "@bit".
ここにコードがあります
create proc p3 @codP int, @codM int, @dela datetime, @panala datetime, @pret smallint, @bit bit output
as
begin
declare @val smallint
set @val = (select COUNT(*)
from OferteSpeciale as OS
where OS.codP = @codP and OS.codM = @codM and
((@panala >= OS.dela and @panala <= OS.panala)
or (@dela >= OS.dela and @dela <= OS.panala) or
(@dela <= OS.dela and @panala >= OS.panala)))
print @val
if (@val = 0)
begin
insert into OferteSpeciale (codP,codM,dela,panala,pret) values (@codP,@codM,@dela,@panala,@pret)
declare @others smallint
set @others = (select COUNT(*)
from Cataloage as c, OferteSpeciale as os
where ((c.codM = @codM and c.codP = @codP and c.pret < @pret) or
(os.codM = @codM and os.codP = @codP and os.pret < @pret)))
if (@others > 0)
set @bit = 0
else
set @bit = 1
end
else
RAISERROR 50001 'There is already a special offer for that product, in that shop, between that dates'
end
declare @bit bit
exec p3 1, 3, '2013-04-15', '2013-04-15', 25, @bit output
