需要nelp向已经很复杂的SQL函数查询添加计数

Question

我有一个SQL Server 2012函数，如下所示：

该功能基本上根据用户标准搜索Web内容的数据库。功能很好。

此处显示了输出样本Results.jpg

我的问题是：正如您从结果中看到的，我能够看到用户是否在ItemRead列中读取了某个项目。

如何修改此SQL函数以允许我输出一个显示读取记录总数的附加列，以便在一次函数调用中返回所需的所有内容。

亲切的问候

Answer 1

如果我理解正确，您可以添加：

SUM(ItemRead) OVER(PARTITION BY UserId) CountRead

修改

根据您的评论，您想要全部，而不是用户：

SUM(ItemRead) OVER(PARTITION BY 1) CountRead
