如何使用sql找出存储过程的依赖关系

Question

我想要一个脚本来显示数据库中存储过程的依赖关系。实际上，当我们手动执行视图依赖时，我有 500 多个存储过程需要很多时间。所以，我想知道这些存储过程是否在数据库中使用，以便我可以删除无用的存储过程。

sp_depends 没有显示所有结果，因为我想要所有依赖于这个存储过程 'usp_Constant_Get_Pvt' 的对象和它所依赖的对象。

EXEC sp_depends @objname = N'usp_Constant_Get_Pvt'

Answer 1

我在类似的情况下使用这个脚本（不要忘记使用架构名称）：

--
DECLARE
    @sp nvarchar(100)
SET @sp = N'dbo.usp_Constant_Get_Pvt'

-- Objects that depends on [@sp]
SELECT 
    referencing_schema_name, 
    referencing_entity_name
FROM sys.dm_sql_referencing_entities(@sp, 'OBJECT')

-- Objects on which [@sp] depends
SELECT 
    referenced_schema_name, 
    referenced_entity_name
FROM sys.dm_sql_referenced_entities(@sp, 'OBJECT')

SELECT
    referenced_schema_name, 
    referenced_entity_name
FROM sys.sql_expression_dependencies
WHERE referencing_id = OBJECT_ID(@sp)

Answer 2

下面的代码将使用表达式依赖关系来找出存储过程的依赖关系。表达式依赖的优点是，它们还可以找到跨数据库依赖。但是，如果有动态 SQL，我们就必须在sql_modules.

引用存储过程的对象

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'SchemaName.StoredProcedureName');  
GO  

存储过程中引用的对象

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_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'SchemaName.StoredProcedureName');  
GO
