sql - 查找 DISTINCT 缺失的 SQL 依赖项

Question

我有一个脚本可以返回数据库中所有无效的依赖项。但是这个脚本返回了很多重复项。所以我只想看到 DISTINCT 结果。

SELECT TOP (100) PERCENT
    QuoteName(OBJECT_SCHEMA_NAME(referencing_id)) + '.' + QuoteName(OBJECT_NAME(referencing_id)) AS [this Object...],
        o.type_desc,
    ISNULL(QuoteName(referenced_server_name) + '.', '')
    + ISNULL(QuoteName(referenced_database_name) + '.', '')
    + ISNULL(QuoteName(referenced_schema_name) + '.', '')
    + QuoteName(referenced_entity_name) AS [... depends ON this missing entity name]
    ,sed.referenced_class_desc
    ,case when o.type_desc in( 'SQL_STORED_PROCEDURE' ,'SQL_SCALAR_FUNCTION' ,'SQL_TRIGGER' ,'VIEW')
          then 'EXEC sys.sp_refreshsqlmodule ''' + QuoteName(OBJECT_SCHEMA_NAME(referencing_id)) + '.' + QuoteName(OBJECT_NAME(referencing_id)) + ''';'
          else null
       end as [Refresh SQL Module command]
FROM sys.sql_expression_dependencies as sed
LEFT JOIN sys.objects o
            ON sed.referencing_id=o.object_id
WHERE (is_ambiguous = 0)
    AND (OBJECT_ID(ISNULL(QuoteName(referenced_server_name) + '.', '')
    + ISNULL(QuoteName(referenced_database_name) + '.', '')
    + ISNULL(QuoteName(referenced_schema_name) + '.', '')
    + QuoteName(referenced_entity_name)) IS NULL)
    AND NOT EXISTS
       (SELECT * 
        FROM sys.types 
        WHERE types.name = referenced_entity_name 
        AND types.schema_id = ISNULL(SCHEMA_ID(referenced_schema_name), SCHEMA_ID('dbo'))
       )
ORDER BY [this Object...],
[... depends ON this missing entity name]
go

这是脚本。

我尝试添加 GROUP BY [... depends ON this missing entity name] 但我收到以下错误:

Invalid column name '... depends ON this missing entity name'.

为了测试，我尝试向结果中的每一列添加聚合函数，但仍然出现同样的错误。

GROUP BY 实际字段名称而不是别名。

SELECT TOP (100) PERCENT
    QuoteName(OBJECT_SCHEMA_NAME(referencing_id)) + '.' + QuoteName(OBJECT_NAME(referencing_id)) AS [this Object...],

    + ISNULL(QuoteName(referenced_database_name) + '.', '')
