我在 SQL Server 2008 上有大约 10 个相当复杂的 SQL 查询 - 但客户端希望能够通过 Crystal Reports XI 从其内部网络（而不是非本地 Web 应用程序）运行它们。

客户端的内部网络不允许我们 (a) 对其专有数据库具有写访问权限，也不允许 (b) 允许我们设置中间 SQL 服务器（这意味着我们不能设置存储过程或其他数据清理）。

SQL 包含row_number() over (partition by col1, col2)、group by col1、 col2 with cube|rollup和/或（多个）pivot 的多个实例。

这甚至可以做到吗？我读过的所有内容似乎都表明这只能通过存储过程实现，我仍然需要先从专有数据库中提取数据。

以下是其中一个查询的精简版本（例如，与功能不直接相关的 JOIN、WHERE 子句和已删除的六列）...


select sum(programID)
    , sum([a.Asian]) as [Episodes - Asian], sum([b.Asian]) as [Eps w/ Next Svc - Asian], sum([c.Asian])/sum([b.Asian]) as [Avg Days to Next Svc - Asian]
    , etc... (repeats for each ethnicity)
from (
    select programID, 'a.' + ethnicity as ethnicityA, 'b.' + ethnicity as ethnicityB, 'c.' + ethnicity as ethnicityC
        , count(*) as episodes, count(daysToNextService) as episodesWithNextService, sum(daysToNextService) as daysToNextService
    from (
        select programID, ethnicity, datediff(dateOfDischarge, nextDateOfService) as daysToNextService from (
            select t1.userID, t1.programID, t1.ethnicity, t1.dateOfDischarge, t1.dateOfService, min(t2.dateOfService) as nextDateOfService
            from TABLE1 as t1 left join TABLE1 as t2
                on datediff(d, t1.dateOfService, t2.dateOfService) between 1 and 31 and t1.userID = t2.userID
            group by t1.userID, t1.programID, t1.ethnicity, t1.dateOfDischarge, t1.dateOfService
        ) as a
    ) as a
    group by programID
) as a
pivot (
    max(episodes) for ethnicityA in ([A.Asian],[A.Black],[A.Hispanic],[A.Native American],[A.Native Hawaiian/ Pacific Isl.],[A.White],[A.Unknown])
) as pA
pivot (
    max(episodesWithNextService) for ethnicityB in ([B.Asian],[B.Black],[B.Hispanic],[B.Native American],[B.Native Hawaiian/ Pacific Isl.],[B.White],[B.Unknown])
) as pB
pivot (
    max(daysToNextService) for ethnicityC in ([C.Asian],[C.Black],[C.Hispanic],[C.Native American],[C.Native Hawaiian/ Pacific Isl.],[C.White],[C.Unknown])
) as pC
group by programID with rollup

Sooooooo.... 这样的东西甚至可以翻译成 Crystal Reports XI 吗？

谢谢！

当您创建报表而不是选择表或存储过程时，请选择add command

这将允许您在其中放置您想要的任何有效的 TSQL 语句。使用公用表表达式 (CTE) 和内联视图我已经设法针对 Oracle 和 SQL Server 创建了一些相当大的复杂语句（超过 400 行），因此它确实是可行的，但是如果您使用参数，您应该考虑使用sp_executesql您将必须弄清楚如何避免 SQL 注入。
