SqlServer 获得存储过程的返回值（参数返回），别玩了output

declare @dingdanid int declare @fanhuizhi int

set @dingdanid = 1

exec 检测订单出库资格 @dingdanid ,@fanhuizhi output   (注意别忘了output否则返回值是NULL)

select @fanhuizhi

create proc dbo.检测订单出库资格

@dingdanID int,     @returnValue int output

as

-- 输入变量 订单编号

set @returnValue = 1

-- 监测订单的出库资格

-- 如果已出库，返回0

-- 如果未出库并且该订单所属的总成需求量均小于等于库存，即满足出库状态,返回1e;否则返回0

if '已出库' = (select 订单状态 from 订单1 where 订单编号 = @dingdanID)

begin

set @returnValue = 0

return @returnValue

end

declare @zongchengID nvarchar(50)

declare @chazhi      int
