Question

我有一个类似于以下内容的查询，以返回与全文搜索匹配的文章。在生产中，文本[FULL TEXT SEARCH CRITERIA]将替换为实际的全文搜索表达式。

编写查询只返回一页结果。

WITH ArtTemp AS (
  SELECT TOP (@StartRow + @MaxRows) ROW_NUMBER() OVER (ORDER BY ArtViews DESC) AS RowID,
  Article.ArtID,Article.ArtTitle,Article.ArtSlug,Category.CatID,Category.CatTitle,
  Article.ArtDescription,Article.ArtCreated,Article.ArtUpdated,Article.ArtUserID,
  [User].UsrDisplayName AS UserName FROM Article
  INNER JOIN Subcategory ON Article.ArtSubcategoryID = Subcategory.SubID
  INNER JOIN Category ON Subcategory.SubCatID = Category.CatID
  INNER JOIN [User] ON Article.ArtUserID = [User].UsrID
  WHERE [FULL TEXT SEARCH CRITERIA] AND Article.ArtApproved = 1
)

SELECT ArtID,ArtTitle,ArtSlug,CatID,CatTitle,ArtDescription,ArtCreated,ArtUpdated,
ArtUserID,UserName FROM ArtTemp
WHERE RowID BETWEEN @StartRow + 1 AND (@StartRow + @MaxRows)
ORDER BY RowID

此工作正常，但全文搜索按相关性顺序返回结果，但ROW_NUMBER() OVER (ORDER BY ArtViews DESC)会对结果进行调整。有没有办法在不诉诸结果的情况下编写相同的查询？

对此的正确答案似乎是使用CONTAINSTABLE，其工作方式类似于CONTAINS但返回表而不是布尔WHERE条件。

所以我最终会得到类似的东西。

WITH ArtTemp AS (
  SELECT TOP (@StartRow + @MaxRows) ROW_NUMBER() OVER (ORDER BY FTS.RANK DESC) AS RowID,
  Article.ArtID,Article.ArtTitle,Article.ArtSlug,Category.CatID,Category.CatTitle,
  Article.ArtDescription,Article.ArtCreated,Article.ArtUpdated,Article.ArtUserID,
  [User].UsrDisplayName AS UserName FROM Article
  INNER JOIN Subcategory ON Article.ArtSubcategoryID = Subcategory.SubID
  INNER JOIN Category ON Subcategory.SubCatID = Category.CatID
  INNER JOIN [User] ON Article.ArtUserID = [User].UsrID
  INNER JOIN CONTAINSTABLE(Article, *, 'FORMSOF(INFLECTIONAL, abc)') AS FTS ON Article.ArtID = FTS.[KEY]
  WHERE Article.ArtApproved = 1
)

SELECT ArtID,ArtTitle,ArtSlug,CatID,CatTitle,ArtDescription,ArtCreated,ArtUpdated,
ArtUserID,UserName FROM ArtTemp
WHERE RowID BETWEEN @StartRow + 1 AND (@StartRow + @MaxRows)
ORDER BY RowID

没有度假的全文搜索结果的返回页面？
