Products 无效 ：SQL server 存储过程
在数据库中有表Product，数据结构与表变量@Products基本相同，除了无有RowNumber.
完成执行后返回消息：'Products'无效。不明就里。请高手不吝赐教@@！###
SO,Here comes Code

CREATE PROCEDURE CatalogGetOriductsOnFrontPromo
(@DescriptionLength INT
@PageNumber INT,
@ProductsPerPAge INT,
@HowManyProducts INT OUTPUT
)

AS

DECLARE @Products TABLE
{
RowNUmber INT,
ProductID INT,
Name NVARCHAR(50),
Description NVARCHAR(MAX),
Price MONEY,
Thumbnail NVARCHAR(50),
Image NVARCHAR(50),
PromoFront bit,
PromoDept bit,
Status binary(50)
}

INSERT INTO @Products
Select Row_Number() over(Order By Product.ProductID),
ProductID,Name,Case when Len(Description)<=@DescriptionLength THEN Description
ELSE Substring (Description,1,@DescriptionLength)+'...' END
AS Description,Price,Thumbnail,Image,PromoFront,PromoDept,Status
Fromo Product
Where PrmoFront=1

Select @HowManyProducts=Count(ProductID) From @Products

Select ProductID, Name,Description,Price,Thumbnail,Image,PromoFront,PromoDept
Status
FROM @Products
WHere RowNumber>(@PageNumber-1)*@ProductsPerPage And
RowNumber<=@PageNumber*@PrductsPerPage

大意就是选取PromoFront为'1'的所有Product,并返回@HowmanyProducts SQL?Server 存储 数据结构
[解决办法]
加个use 数据库名
go
CREATE PROCEDURE CatalogGetOriductsOnFrontPromo
(@DescriptionLength INT
@PageNumber INT,
@ProductsPerPAge INT,
@HowManyProducts INT OUTPUT
)

AS

DECLARE @Products TABLE
{--用括号
RowNUmber INT,
ProductID INT,
Name NVARCHAR(50),
Description NVARCHAR(MAX),
Price MONEY,
Thumbnail NVARCHAR(50),
Image NVARCHAR(50),
PromoFront bit,
PromoDept bit,
Status binary(50)
}

--用括号

INSERT INTO @Products
Select Row_Number() over(Order By Product.ProductID),
ProductID,Name,Case when Len(Description)<=@DescriptionLength THEN Description
ELSE Substring (Description,1,@DescriptionLength)+'...' END
AS Description,Price,Thumbnail,Image,PromoFront,PromoDept,Status
Fromo Product
Where PrmoFront=1

Select @HowManyProducts=Count(ProductID) From @Products

Select ProductID, Name,Description,Price,Thumbnail,Image,PromoFront,PromoDept
Status
FROM @Products
WHere RowNumber>(@PageNumber-1)*@ProductsPerPage And
RowNumber<=@PageNumber*@PrductsPerPage
[解决办法]
try this,

CREATE PROCEDURE CatalogGetOriductsOnFrontPromo
(@DescriptionLength int,
 @PageNumber INT,
 @ProductsPerPAge INT,
 @HowManyProducts INT OUTPUT)
AS
begin
DECLARE @Products TABLE
(RowNUmber INT,
 ProductID INT,
 Name NVARCHAR(50),
 Description NVARCHAR(MAX),
 Price MONEY,
 Thumbnail NVARCHAR(50),
 Image NVARCHAR(50),
 PromoFront bit,
 PromoDept bit,
 Status binary(50))
 
INSERT INTO @Products
 Select Row_Number() over(Order By Product.ProductID),
        ProductID,Name,Case when Len(Description)<=@DescriptionLength THEN Description
        ELSE Substring (Description,1,@DescriptionLength)+'...' END
        AS Description,Price,Thumbnail,Image,PromoFront,PromoDept,Status
 From Product
 Where PrmoFront=1

Select @HowManyProducts=Count(ProductID) From @Products
 
Select ProductID, Name,Description,Price,Thumbnail,Image,PromoFront,PromoDept,Status
  FROM @Products
  WHere RowNumber>(@PageNumber-1)*@ProductsPerPage And
        RowNumber<=@PageNumber*@ProductsPerPage
end
