C# SQL Server 2008-具有多个关键字和分页的全文搜索

我不是一个数据库专家（这个问题会说明）。我正在尝试编写一个表值函数，可以在ASP.NET web应用程序中与Linq to Sql一起使用

假设我想搜索标题或摘要可能包含许多关键词的书籍（例如“澳大利亚历史”）

我希望一次显示x个结果，因此我需要能够告诉我的函数“跳过”和“获取”一定数量的记录

有些书可能被标记为“已删除”。我不想退回这些

以下是我目前掌握的情况：

CREATE FUNCTION SearchBooks
(
    @keywords nvarchar(50),
    @skip int,
    @take int
)
RETURNS TABLE
AS
RETURN
(
  SELECT TOP (@take)
         ROW_NUMBER() OVER (ORDER BY MyFTS.RANK DESC) AS RowID,
         MyFTS.RANK as Relevance,
         [ID],
         [Title],
         [Summary]
    FROM [Book]
    JOIN CONTAINSTABLE ([Book], ([Title], [Summary]), @keywords, @take) AS MyFTS ON MyFTS.[KEY] = [Book].[ID]
   WHERE ([Book].[Deleted] = 0) 
     AND (MyFTS.[RowID] BETWEEN (@skip + 1) AND (@skip + @take))
ORDER BY MyFTS.RANK DESC
)

当我尝试创建此函数时，SSMS会给出错误“无效列名'RowID'”

我想我还需要获得匹配记录的总数，以便设置分页

我希望你们中的一位SQL专家能为我指明正确的方向。

您不能在WHERE子句中引用列别名-使用内联视图/派生表：

  SELECT x.rowid,
         x.relevance,
         x.id,
         x.title,
         x.summary
   FROM (SELECT TOP (@take)
                ROW_NUMBER() OVER (ORDER BY MyFTS.RANK DESC) AS RowID,
                MyFTS.RANK as Relevance,
                [ID],
                [Title],
                [Summary]
           FROM [Book] b
           JOIN CONTAINSTABLE ([Book], ([Title], [Summary]), @keywords, @take) AS MyFTS ON MyFTS.[KEY] = b.id
          WHERE b.[Deleted] = 0) AS x
    WHERE x.[RowID] BETWEEN (@skip + 1) AND (@skip + @take))
ORDER BY x.relevance DESC

谢谢我的小马，这正是我想要的。 我已经修改了这个函数，这样它也会返回匹配行的总数（TotalRows），现在我应该可以让分页工作正常了

CREATE FUNCTION SearchBooks
(
    @keywords nvarchar(50),
    @skip int,
    @take int
)
RETURNS TABLE
AS
RETURN
(
    SELECT TOP (@take) * FROM 
    (
        SELECT TOP (@take)
            ROW_NUMBER() OVER (ORDER BY MyFTS.RANK DESC) AS RowID,
            COUNT(*) OVER(PARTITION BY 1) as TotalRows,
            MyFTS.RANK as Relevance,
            [ID],
            [Title],
            [Summary]
        FROM [Book] b
        JOIN CONTAINSTABLE ([Book], ([Title], [Summary]), @keywords, @take) AS MyFTS ON MyFTS.[KEY] = b.[ID]
        WHERE b.[Deleted] = 0
    ) AS x
    WHERE x.[RowID] BETWEEN (@skip + 1) AND (@skip + @take)
    ORDER BY x.relevance DESC
)
