SQL数据透视表错误

Question

大家好，当我在asp.net上调用存储过程时，我收到此错误 -

  

过程或函数'uspTargetQuantites'需要参数   “@Product”，未提供。

我的存储过程...

USE [WorkstationCells]
GO
/****** Object:  StoredProcedure [dbo].[uspTargetQuantites]    Script Date: 11/04/2018 08:27:38 ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
ALTER PROCEDURE [dbo].[uspTargetQuantites] (@Product VARCHAR(10))
AS

SET NOCOUNT ON

/* debug */
--DECLARE @Product VARCHAR(10)
--SET @Product = 'G120C'
/* debug */


SELECT Product 
              , Framesize 
              , HourName 
              , Quantity 
INTO #PivotData
FROM WorkstationCells.dbo.TargetQuantites
WHERE Product = @Product


SELECT DISTINCT Framesize INTO #PivotDataProducts FROM #PivotData


DECLARE @PivotColumnHeaders VARCHAR(MAX)
SELECT @PivotColumnHeaders = 
  COALESCE(
    @PivotColumnHeaders + ',[' + cast(Framesize as varchar) + ']',
    '[' + cast(Framesize as varchar)+ ']'
  )
FROM #PivotDataProducts    

DECLARE @PivotTableSQL NVARCHAR(MAX)
SET @PivotTableSQL = N'
SELECT * FROM #PivotData AS PivotData
      PIVOT (SUM(Quantity)FOR Framesize IN (' + @PivotColumnHeaders + ')) AS PivotTable
'

EXECUTE(@PivotTableSQL)

DROP TABLE #PivotData
DROP TABLE #PivotDataProducts


--EXEC uspTargetQuantites 'G120C'

谁能告诉我哪里出错了？？

这是我的c＃代码...来调用SP

    public void Refreshdata()
    {

        SqlConnection con = new SqlConnection(@"Server=(LocalDB)\v11.0;Database=WorkstationCells");
        SqlCommand cmd = new SqlCommand("[dbo].[uspTargetQuantites]", con);
        SqlDataAdapter sda = new SqlDataAdapter(cmd);
        DataSet ds = new DataSet();
        sda.Fill(ds);
        GridView1.DataSource = ds;
        GridView1.DataBind();
    }
}

}
