Question

我们有一个在我们的应用程序中使用的51个存储过程的列表。

我需要找出那些存储过程调用的所有函数和存储过程的名称

有没有快速的方法可以找出我们的存储过程正在调用的内容？

我尝试使用 sys.dm_sql_referencing_entities ，如下所示

SELECT 
referencing_schema_name +'.'+ referencing_entity_name AS ReferencedEntityName,
referencing_class_desc AS ReferencingEntityDescription 
FROM sys.dm_sql_referencing_entities ('dbo.sp_GetPayRunDetails', 'OBJECT');
GO

但是我希望有一种方法可以检查所有50个存储过程，并获得有关他们调用的其他对象（存储过程和函数）的详细信息......

我不想手动执行此操作是因为我还需要对存储的proc和函数进行递归依赖...

此查询可能会为您解决问题：

WITH cteDependencies AS (
    SELECT e.referencing_id object_id, e.referencing_id, e.referenced_id, e.referenced_schema_name, e.referenced_entity_name
    FROM sys.sql_expression_dependencies e
    WHERE e.referencing_id = OBJECT_ID('dbo.sp_GetPayRunDetails')
    UNION ALL
    SELECT d.object_id, e.referencing_id, e.referenced_id, e.referenced_schema_name, e.referenced_entity_name
    FROM sys.sql_expression_dependencies e
    JOIN cteDependencies d ON d.referenced_id = e.referencing_id AND e.referenced_id <> e.referencing_id
)
SELECT OBJECT_NAME(d.object_id) source_name, d.*
    FROM cteDependencies d
    JOIN sys.all_objects o ON d.referenced_id = o.object_id
    WHERE o.[type] IN ('P','FN','TF'); -- for a list of types see https://msdn.microsoft.com/en-us/library/ms178618.aspx?f=255&MSPPError=-2147217396

请注意，循环引用会失败;如果你有这样的话，你需要跟踪依赖路径（例如在XML列中）并跳过重复的项目。

您可以通过更改OBJECT_ID('dbo.sp_GetPayRunDetails')过滤器来更改“来源”，以包含您要分析的SP。

我有一个功能。根据您的方式修改它。它管理自我引用

CREATE FUNCTION GetDependents(    
 @ObjectName AS SYSNAME    
)

RETURN
