系统函数： sys.dm_sql_referencing_entities

此函数用于显示依赖于过程的对象。

1.第一个示例创建 uspVendorAllInfo 过程，该过程返回 Adventure Works Cycles 数据库中所有供应商的名称、所提供的产品、信用等级以及可用性。

IF OBJECT_ID ( 'Purchasing.uspVendorAllInfo', 'P' ) IS NOT NULL   
    DROP PROCEDURE Purchasing.uspVendorAllInfo;  
GO  
CREATE PROCEDURE Purchasing.uspVendorAllInfo  
WITH EXECUTE AS CALLER  
AS  
    SET NOCOUNT ON;  
    SELECT v.Name AS Vendor, p.Name AS 'Product name',   
      v.CreditRating AS 'Rating',   
      v.ActiveFlag AS Availability  
    FROM Purchasing.Vendor v   
    INNER JOIN Purchasing.ProductVendor pv  
      ON v.BusinessEntityID = pv.BusinessEntityID   
    INNER JOIN Production.Product p  
      ON pv.ProductID = p.ProductID   
    ORDER BY v.Name ASC;  
GO

2.创建该过程后，第二个示例使用 sys.dm_sql_referencing_entities 函数来显示依赖于该过程的对象。

USE AdventureWorks2012;  
GO  
SELECT referencing_schema_name, referencing_entity_name, referencing_id, referencing_class_desc, is_caller_dependent  
FROM sys.dm_sql_referencing_entities ('Purchasing.uspVendorAllInfo', 'OBJECT');   
GO

此函数用于显示过程所依赖的对象。

1.创建存储过程，该过程返回 Adventure Works Cycles 数据库中所有供应商的名称、所提供的产品、信用等级以及可用性。

USE AdventureWorks2008R2;  
GO  
IF OBJECT_ID ( 'Purchasing.uspVendorAllInfo', 'P' ) IS NOT NULL   
    DROP PROCEDURE Purchasing.uspVendorAllInfo;  
GO  
CREATE PROCEDURE Purchasing.uspVendorAllInfo  
WITH EXECUTE AS CALLER  
AS  
    SET NOCOUNT ON;  
    SELECT v.Name AS Vendor, p.Name AS 'Product name',   
      v.CreditRating AS 'Rating',   
      v.ActiveFlag AS Availability  
    FROM Purchasing.Vendor v   
    INNER JOIN Purchasing.ProductVendor pv  
      ON v.BusinessEntityID = pv.BusinessEntityID   
    INNER JOIN Production.Product p  
      ON pv.ProductID = p.ProductID   
    ORDER BY v.Name ASC;  
GO

2.使用 sys.dm_sql_referenced_entities 函数来显示该过程依赖的对象

USE AdventureWorks2012;  
GO  
SELECT referenced_schema_name, referenced_entity_name,  
referenced_minor_name,referenced_minor_id, referenced_class_desc,  
is_caller_dependent, is_ambiguous  
FROM sys.dm_sql_referenced_entities ('Purchasing.uspVendorAllInfo', 'OBJECT');  
GO

对象目录视图： sys.sql_expression_dependencies

显示依赖于过程的对象。

1.创建存储过程，

IF OBJECT_ID ( 'Purchasing.uspVendorAllInfo', 'P' ) IS NOT NULL   
    DROP PROCEDURE Purchasing.uspVendorAllInfo;  
GO  
CREATE PROCEDURE Purchasing.uspVendorAllInfo  
WITH EXECUTE AS CALLER  
AS  
    SET NOCOUNT ON;  
    SELECT v.Name AS Vendor, p.Name AS 'Product name',   
      v.CreditRating AS 'Rating',   
      v.ActiveFlag AS Availability  
    FROM Purchasing.Vendor v   
    INNER JOIN Purchasing.ProductVendor pv  
      ON v.BusinessEntityID = pv.BusinessEntityID   
    INNER JOIN Production.Product p  
      ON pv.ProductID = p.ProductID   
    ORDER BY v.Name ASC;  
GO

2.使用 sys.sql_expression_dependencies 视图来显示依赖于该过程的对象。

USE AdventureWorks2012;  
GO  
SELECT OBJECT_SCHEMA_NAME ( referencing_id ) AS referencing_schema_name,  
    OBJECT_NAME(referencing_id) AS referencing_entity_name,   
    o.type_desc AS referencing_desciption,   
    COALESCE(COL_NAME(referencing_id, referencing_minor_id), '(n/a)') AS referencing_minor_id,   
    referencing_class_desc, referenced_class_desc,  
    referenced_server_name, referenced_database_name, referenced_schema_name,  
    referenced_entity_name,   
    COALESCE(COL_NAME(referenced_id, referenced_minor_id), '(n/a)') AS referenced_column_name,  
    is_caller_dependent, is_ambiguous  
FROM sys.sql_expression_dependencies AS sed  
INNER JOIN sys.objects AS o ON sed.referencing_id = o.object_id  
WHERE referenced_id = OBJECT_ID(N'Purchasing.uspVendorAllInfo')  
GO

显示过程所依赖的对象。

IF OBJECT_ID ( 'Purchasing.uspVendorAllInfo', 'P' ) IS NOT NULL   
    DROP PROCEDURE Purchasing.uspVendorAllInfo;  
GO  
CREATE PROCEDURE Purchasing.uspVendorAllInfo

AS  
    SET NOCOUNT ON;  
    SELECT v.Name AS Vendor, p.Name AS 'Product name',   
      v.CreditRating AS 'Rating',   
      v.ActiveFlag AS Availability  
    FROM Purchasing.Vendor v   
    INNER JOIN Purchasing.ProductVendor pv  
      ON v.BusinessEntityID = pv.BusinessEntityID   
    INNER JOIN Production.Product p  
      ON pv.ProductID = p.ProductID   
    ORDER BY v.Name ASC;  
GO

SELECT OBJECT_NAME(referencing_id) AS referencing_entity_name,   
    o.type_desc AS referencing_desciption,   
    COALESCE(COL_NAME(referencing_id, referencing_minor_id), '(n/a)') AS referencing_minor_id,   
    referencing_class_desc, referenced_class_desc,  
    referenced_server_name, referenced_database_name, referenced_schema_name,  
    referenced_entity_name,   
    COALESCE(COL_NAME(referenced_id, referenced_minor_id), '(n/a)') AS referenced_column_name,  
    is_caller_dependent, is_ambiguous  
FROM sys.sql_expression_dependencies AS sed  
INNER JOIN sys.objects AS o ON sed.referencing_id = o.object_id  
WHERE referencing_id = OBJECT_ID(N'Purchasing.uspVendorAllInfo');  
GO
