Question

Maintenant, j'ai écrit la couche businessLogic.

Dans ce projet, le nom de la colonne de table sont:

Product, 
UM, 
ProductGroup, 
ProductCode, 
ProductName, 
BuyingPrice, 
SellingPrice, 
IsActive, 
IsDeleted 

puis

j'ai écrit des procédures stockées, ils sont:

1. Product_SelectList 
2. Product_SelectByProduct 
3. Product_SelectByUM 
4. Product_SelectByProductType 
5. Product_SelectByProductGroup 
6. Product_Insert 
7. Prodct_Update 
8. Product_DeleteByProduct 
9. Product_DeleteUM 
10. Product_DeleteByProductType 
11. Product_DeleteByProductGroup 

j'ai écrit Product_SelectByProduct procédure stockée

set ANSI_NULLS ON 
set QUOTED_IDENTIFIER ON 
GO 
ALTER Procedure [dbo].[Product_SeleteByProduct] 
@Product char(36) 
AS 
Begin 
Select 
Product, 
UM, 
ProductType, 
ProductGroup, 
ProductCode, 
ProductName, 
BuyingPrice, 
SellingPrice, 
IsActive, 
IsDeleted 
from Product 
Where Product=@Product 
End

     public void Update(ProductInfo productInfo) 
     { 
      dataAccess.Update(productInfo.Product, productInfo.UM, productInfo.ProductType,

     public ProductInfo SeletcByProduct(string Product) 
     { 
      IDataReader Reader = dataAccess.SelectByProduct(Product); 
      ProductInfo productInfo = new ProductInfo(); 

      if (Reader.Read()) 
      { 
       productInfo.Product = Convert.ToString(Reader["Product"]); 
       productInfo.UM = Convert.ToString(Reader["UM"]); 
       productInfo.ProductType = Convert.ToString(Reader["ProductType"]); 
       productInfo.ProductGroup = Convert.ToString(Reader["ProductGroup"]); 
       productInfo.ProductCode = Convert.ToString(Reader["ProductCode"]); 
       productInfo.ProductName = Convert.ToString(Reader["ProductName"]); 
       productInfo.BuyingPrice = Convert.ToString(Reader["BuyingPrice"]); 
       productInfo.SellingPrice = Convert.ToString(Reader["SellingPrice"]); 
       productInfo.IsActive = Convert.ToBoolean(Reader["IsActive"]); 
       productInfo.IsDeleted = Convert.ToBoolean(Reader["IsDeleted"]); 

      } 
      Reader.Close(); 
      return productInfo; 
     } 

Maintenant, je voudrais Product_SelectByProductType

c'est la procédure stockée de Product_SelectByProductType

set ANSI_NULLS ON 
set QUOTED_IDENTIFIER ON 
GO 

ALTER Procedure [dbo].[Product_SelectByProductType] 
@ProductType char(36) 
As 
Begin 
Select 
ProductType, 
ProductTypeDescription, 
IsActive, 
IsDefault, 
IsDeleted 
from ProductType 
Where ProductType=@ProductType 
End
