如何在 ArticleViews 列中输出具有最高值的前 5 个结果 [重复]

Question

下面是我的数据源。

<asp:SqlDataSource ID="getbyviews" runat="server" ConnectionString="<%$ ConnectionStrings:ConnectAntiFrack %>" 
SelectCommand="SELECT [ArticleID], [ArticleTitle], [ArticlePublished], [ArticleViews] 
FROM [ArticlesTBL] 
WHERE ([ArticlePublished] = @ArticlePublished) 
ORDER BY [ArticleViews] DESC">
<SelectParameters>
<asp:Parameter DefaultValue="True" Name="ArticlePublished" Type="Boolean" />
</SelectParameters>
</asp:SqlDataSource>

有没有办法操纵 select 语句只获取 5 个最高的结果？或者这可以在 C# 中完成吗？ 我的数据源稍后将用于填充列表视图。

Answer 1

只需使用TOP 5:

SELECT TOP 5 [ArticleID], [ArticleTitle], [ArticlePublished], [ArticleViews] 
FROM [ArticlesTBL] 
WHERE ([ArticlePublished] = @ArticlePublished) 
ORDER BY [ArticleViews] DESC
