SQL：在多列上检查（其中只有一列必须不为空）

Question

好的，

所以我有如下报告：

WITH   StudentCTEm ([Person Code], [Course Instance Maths], [Course Occurrence Maths], [Course Title], [ULN], [Main Aim])
AS     (SELECT [Person Code],
               [Course Instance],
               [Course Occurrence],
               [Course Title],
               [ULN],
               [Main Aim]
        FROM   EBSWarehouse.dbo.StudentEnrolment cte
        WHERE  cte.[Progress Status] = 'A' AND cte.[Course Instance] LIKE '%REGM%' AND cte.[Course Occurrence] LIKE '1920%'),
StudentCTEe ([Person Code], [Course Instance English], [Course Occurrence English], [Course Title], [ULN], [Main Aim])
AS     (SELECT [Person Code],
               [Course Instance],
               [Course Occurrence],

               [ULN],
               [Main Aim]
        FROM   EBSWarehouse.dbo.StudentEnrolment cte
        WHERE  cte.[Progress Status] = 'A' AND cte.[Course Instance] LIKE '%REGE%' AND cte.[Course Occurrence] LIKE '1920%'),
StudentCTEIT ([Person Code], [Course Instance IT], [Course Occurrence IT], [Course Title], [ULN], [Main Aim])

               [ULN],
               [Main Aim]
        FROM   EBSWarehouse.dbo.StudentEnrolment cte
        WHERE  cte.[Progress Status] = 'A' AND cte.[Course Instance] LIKE '%REGIT%' AND cte.[Course Occurrence] LIKE '1920%'),
pcsCTEfsM ([Learning Aim Ref Maths], [Learning Aim Desc Maths], [PICS ID], [Funding End])

               [Learning Aim Desc],

        FROM   dbo.ILRComponentAim cte
        WHERE [Learning Aim Desc] like '%Functional Skills qualification in Mathematics%'),
pcsCTEfsE ([Learning Aim Ref English], [Learning Aim Desc English], [PICS ID], [Funding End])
AS     (SELECT [Learning Aim Ref],
               [Learning Aim Desc],
               [PICS ID],
               [Funding End]
        FROM   dbo.ILRComponentAim cte
        WHERE [Learning Aim Desc] like '%Functional Skills qualification in English%'),
pcsCTEfsIT ([Learning Aim Ref IT], [Learning Aim Desc IT], [PICS ID], [Funding End])
AS     (SELECT [Learning Aim Ref],
               [Learning Aim Desc],
               [PICS ID],
               [Funding End]
        FROM   dbo.ILRComponentAim cte
        WHERE [Learning Aim Desc] like '%Functional Skills qualification in Information%')


SELECT DISTINCT

WHERE s.[Episode End] is null AND s.[Status] = 'L' AND [Learning Aim End] is null AND icm.[Funding End] is null AND sen.[Main Aim] <> 1 
ORDER BY s.[Person Code] ASC

某些记录显示空为：

    SELECT 
    icm.[Learning Aim Ref Maths],
    ICm.[Learning Aim Desc Maths],
    Sem.[Course Instance Maths],
    Sem.[Course Occurrence Maths],
    SEm.[Course Title],
    ice.[Learning Aim Ref English],
    ICe.[Learning Aim Desc English],
    See.[Course Instance English],
    See.[Course Occurrence English],
    SEe.[Course Title],
    icit.[Learning Aim Ref IT],
    icit.[Learning Aim Desc IT],
    Seit.[Course Instance IT],
    Seit.[Course Occurrence IT],
    SEIT.[Course Title]
    ...

哪个很好。

如何在我的WHERE子句中仅显示上面至少一列不为空的记录

感谢

我知道这是肮脏的报告写作，但这是一项需要做的快速工作

告诉我添加更多详细信息：

如果您想要上下文是的，因此，这基本上是在各个表和另一个数据库之间进行映射，以准确计算谁正在使用其PICS（内部软件）学徒课程进行功能技能课程，以及我们在内部学生管理系统上拥有的信息。

我应该添加预期结果与实际结果相同，对于GDPR，我无法真正发布结果集），但实际上我需要做的就是忽略报告中所有记录均为'null'的记录课程选项（基本上有些人撤回或完成了他们的FS部分，但没有撤回他们的WBL课程，因此出现在此报告中，我尝试使用“完成状态”列省略记录，但有些人被认为仍处于活动状态，并且从很久以前就离开了-所以这是不行的，所以我唯一的选择就是我正在整理的duuuurty小视图

COALESCE？
