私はSQLServerを初めて使用し、現在それを学んでいます。わからないストアドプロシージャをたどりました。

-- declare a new TABLE variable
DECLARE @Products TABLE
(RowNumber INT,
ProductID INT,
Name VARCHAR(50),
Description VARCHAR(5000),
Price MONEY,
Image1FileName VARCHAR(50),
Image2FileName VARCHAR(50),
OnDepartmentPromotion bit,
OnCatalogPromotion bit)

-- populate the table variable with the complete list of products
INSERT INTO @Products
SELECT ROW_NUMBER() OVER (ORDER BY Product.ProductID),
Product.ProductID, Name,
SUBSTRING(Description, 1, @DescriptionLength) + '...' AS Description, Price,
Image1FileName, Image2FileName, OnDepartmentPromotion, OnCatalogPromotion
FROM Product INNER JOIN ProductCategory
ON Product.ProductID = ProductCategory.ProductID
WHERE ProductCategory.CategoryID = @CategoryID
-- return the total number of products using an OUTPUT variable
SELECT @HowManyProducts = COUNT(ProductID) FROM @Products
-- extract the requested page of products
SELECT ProductID, Name, Description, Price, Image1FileName,
Image2FileName, OnDepartmentPromotion, OnCatalogPromotion
FROM @Products
WHERE RowNumber > (@PageNumber - 1) * @ProductsPerPage
AND RowNumber <= @PageNumber * @ProductsPerPage

お願いします！上記のストアドプロシージャを単純なt-sqlステートメントに変換して、これらのポイントを取得します。私はあなたの仕事に本当に感謝します。

前もって感謝します

このようなものは機能します（私はそれをテストしませんでした）：

--extract the requested page of products
SELECT ProductID, Name, Description, Price, Image1FileName,
Image2FileName, OnDepartmentPromotion, OnCatalogPromotion
FROM (
SELECT ROW_NUMBER() OVER (ORDER BY Product.ProductID) AS RowNumber,
Product.ProductID, Name,
SUBSTRING(Description, 1, @DescriptionLength) + '...' AS Description, Price,
Image1FileName, Image2FileName, OnDepartmentPromotion, OnCatalogPromotion
FROM Product INNER JOIN ProductCategory
ON Product.ProductID = ProductCategory.ProductID
WHERE ProductCategory.CategoryID = @CategoryID
    ) A
WHERE RowNumber > (@PageNumber - 1) * @ProductsPerPage
AND RowNumber <= @PageNumber * @ProductsPerPage

-- return the total number of products using an OUTPUT variable
SELECT COUNT(ProductID) AS ProductCount FROM Product INNER JOIN ProductCategory
ON Product.ProductID = ProductCategory.ProductID
WHERE ProductCategory.CategoryID = @CategoryID
