SQL和ADO.net:使用输出参数指定的参数太多

您已经发布了程序“uspGetOrderTrackingHeaderInfo”的代码，并且正在调用该程序“uspInsertOrderTrackinInfo”。可能您修改了错误的进程，并且在Insert进程上没有输出。

请注意，您也可以将cmd对象添加到using语句中。然后让调用方法处理任何异常。

ALTER PROCEDURE dbo.uspGetOrderTrackingHeaderInfo
  @ContractID varchar(9)
, @SalesRepID int
, @StatusID int
, @TypeID int
, @StartDate datetime
, @EndDate datetime
, @Identity int = null output

INSERT INTO [dbo].[tblOrderTracking]
           ([ContractID]
