Sql 按从组中选择字段

我已完成此查询，但由于group by子句，无法选择所有字段

如何重新格式化查询，使其检索所有信息？ 我尝试按每个字段分组，但其中一些是文本

SELECT p.Pato_Id, p.Description, p.Dated a.Assessment_Id, a.Recommendation, Question1 = MAX(CASE WHEN r.Question_Id = 0 THEN r.Answer_Id END), Question2 = MAX(CASE WHEN r.Question_Id = 1 THEN r.Answer_Id END) FROM Patos p OUTER APPLY ( SELECT TOP 1 a.Assessment_Id , a.Recommendation FROM Assessments a WHERE a.Pato_Id = p.Pato_Id ORDER BY a.Dated DESC ) a JOIN Replies r ON a.Assessment_Id = r.Assessment_Id GROUP BY p.Pato_Id

---

尝试将文本字段强制转换为nvarcharmax，然后包括group by中的所有字段，例如：

SELECT 
    p.Pato_Id,
    CAST(p.Description AS nvarchar(max)),
    p.Dated,
    a.Assessment_Id,
    a.Recommendation,
    Question1 = MAX(CASE WHEN r.Question_Id = 0 THEN r.Answer_Id END),
    Question2 = MAX(CASE WHEN r.Question_Id = 1 THEN r.Answer_Id END)
FROM Patos p
OUTER APPLY (
    SELECT TOP 1 
        a.Assessment_Id
        , a.Recommendation
    FROM Assessments a
    WHERE a.Pato_Id = p.Pato_Id
    ORDER BY a.Dated DESC
    ) a
JOIN Replies r
ON a.Assessment_Id = r.Assessment_Id
GROUP BY 
    p.Pato_Id,
    CAST(p.Description AS nvarchar(max)),
    p.Dated,
    a.Assessment_Id,
    a.Recommendation

哪个是文本栏？假设是p.Description，则可以执行以下操作：

SELECT sub.*, t.Description FROM
(SELECT 
    p.Pato_Id as Pato_Id,
    t.Description as Description,
    t.Dated as Dated,
    a.Assessment_Id as Assessment_Id,
    a.Recommendation as Recommendation,
    Question1 = MAX(CASE WHEN r.Question_Id = 0 THEN r.Answer_Id END),
    Question2 = MAX(CASE WHEN r.Question_Id = 1 THEN r.Answer_Id END)
FROM Patos p
OUTER APPLY (
    SELECT TOP 1 
        a.Assessment_Id
        , a.Recommendation
    FROM Assessments a
    WHERE a.Pato_Id = p.Pato_Id
    ORDER BY a.Dated DESC
    ) a
JOIN Replies r
ON a.Assessment_Id = r.Assessment_Id
GROUP BY 
    p.Pato_Id,
    a.Assessment_Id,
    a.Recommendation) AS sub
INNER JOIN Patos t ON
    t.Pato_Id = sub.Pato_Id

如果您的团队也被推荐为：

GROUP BY 
    p.Pato_Id,
    a.Assessment_Id

您也可以加入该表。

当我尝试通过将所有字段添加到组中时，会出现以下错误：文本、ntext和图像数据类型无法进行比较或排序，除非使用IS NULL或LIKE运算符。我无法执行此操作。我必须按原样归还一切。我想用一种方法将查询拆分为两个选择，但我不知道该怎么做。另一种方法是将分组的查询连接回其他值的查询？是的，我就是这么想的。我该怎么做呢？更新了一些选项当我放置内部连接时，它显示：关键字“INNER”附近的语法不正确
