Sql 取消激活列时键入强制转换错误，原因是什么？

我正试图取消选中mdsb.sys.database表中的某些列，但某些列出现问题。在取消激活该表之前，我尝试将CTE中的所有列强制转换为NVARCHAR（128），但仍然不起作用。有人能解释为什么以及如何解决这个问题吗

;
WITH props AS (
SELECT 
    [name]
    ,CAST([collation_name] AS NVARCHAR(128)) AS [collation_name]
    ,CAST([is_auto_close_on] AS NVARCHAR(128)) AS [is_auto_close_on]
    ,CAST([is_auto_shrink_on] AS NVARCHAR(128)) AS [is_auto_shrink_on]
    ,CAST([is_auto_create_stats_on] AS NVARCHAR(128)) AS [is_auto_create_stats_on]
    ,CAST([is_auto_update_stats_async_on] AS NVARCHAR(128)) AS [is_auto_update_stats_async_on]
    ,CAST([is_auto_update_stats_on] AS NVARCHAR(128)) AS [is_auto_update_stats_on]
    ,CAST(CASE WHEN [is_parameterization_forced] = 0 THEN N'SIMPLE' ELSE N'FORCED' END AS NVARCHAR(128)) AS [is_parameterization_forced]
    ,CAST([is_trustworthy_on] AS NVARCHAR(128)) AS [is_trustworthy_on]
    ,CAST([compatibility_level] AS NVARCHAR(128)) AS [compatibility_level]
    ,CAST([page_verify_option_desc] AS NVARCHAR(128)) AS [page_verify_option_desc]
FROM sys.databases s
WHERE [name] = DB_NAME()
)
SELECT [name]
        ,[property]
        ,[value] 
FROM [props]
UNPIVOT
(
    [value]
    FOR [property] IN ([collation_name] 
                        ,[is_auto_close_on]
                        ,[is_auto_shrink_on]
                        ,[is_auto_create_stats_on]
                        ,[is_auto_update_stats_async_on]
                        ,[is_auto_update_stats_on]
                        ,[is_parameterization_forced]
                        ,[is_trustworthy_on]
                        ,[compatibility_level]
                        ,[page_verify_option_desc]
                        )
) AS u

错误：

Msg 8167, Level 16, State 1, Line 34
The type of column "page_verify_option_desc" conflicts with the type of other columns specified in the UNPIVOT list.

结果应该是这样的，但带有“page\u verify\u option\u desc”行和“recovery\u model\u desc”

我认为这实际上是一个排序问题

像这样试试

    [name]

    ,CAST([is_auto_close_on] AS NVARCHAR(128)) AS [is_auto_close_on]

    ,CAST([is_auto_create_stats_on] AS NVARCHAR(128)) AS [is_auto_create_stats_on]
    ,CAST([is_auto_update_stats_async_on] AS NVARCHAR(128)) AS [is_auto_update_stats_async_on]
    ,CAST([is_auto_update_stats_on] AS NVARCHAR(128)) AS [is_auto_update_stats_on]

FROM sys.databases s
WHERE [name] = DB_NAME()
)
SELECT [name]
        ,[property]
        ,[value] 
FROM [props]
UNPIVOT
(
    [value]
    FOR [property] IN ([collation_name] 
                        ,[is_auto_close_on]
                        ,[is_auto_shrink_on]
                        ,[is_auto_create_stats_on]
                        ,[is_auto_update_stats_async_on]
                        ,[is_auto_update_stats_on]
                        ,[is_parameterization_forced]

                        ,[page_verify_option_desc]
                        )
) AS u

这就像我不能做一个演员在unpivot。我以前必须这么做。哦，你有没有试过校对数据库？我已经用校对数据库？默认值更新了。请查收it@DanielBjörk-view

sys.databases

从具有资源数据库排序规则的

sys.syspalvalues

中提取描述文本。从sys.databases运行

SELECT*，其中page\u verify\u option\u desc=collation\u name

也会产生排序规则冲突。在MS SQL SERVER中，可以在列级别设置排序规则。比较查询中的两个不同排序规则列时，会出现此错误。
