我该如何检查sql server的'views'依赖关系

Question

有没有一种方法可以找出使用自定义查询或存储过程的视图正在使用哪些基表？

Answer 1

如果这是你经常在做的事情，那么Red Gate SQL Dependency Tracker（不，我不为他们工作）是一个很好的工具。如果你想尝试一下，我认为他们有试用期。

这里有一个很好的解释：

Answer 3

您可以使用sql_dependencies观点：

select OBJECT_NAME(referenced_major_id) as DependantObject 
from sys.sql_dependencies 
where object_id = object_id('YourViewName') 

要递归检索依赖（FE，如果从一个视图中选择，这将发现的表是另一种观点认为引用）：

with deps (child, parent) as (
    select d.object_id, d.referenced_major_id 
    from sys.sql_dependencies d 
    where d.object_id = object_id('YourViewName') 
    union all 
    select d.object_id, d.referenced_major_id 
    from sys.sql_dependencies d 
    inner join deps on deps.parent = d.object_id 
) 
select OBJECT_NAME(parent) 
from deps 

此方法不是傻瓜证明。例如，如果使用sp_rename重命名对象，则其依赖关系不会更新。

您可以使用sys.dm_sql_referenced_entities功能来查找指定的视图中引用的对象：

SELECT DISTINCT 
referenced_schema_name , 
referenced_entity_name 
FROM sys.dm_sql_referenced_entities ('Sales.vSalesPersonSalesByFiscalYears', 'OBJECT'); 

此外，有sys.sql_expression_dependencies系统视图，您可以指定表名和类型引用对象的：

SELECT 
referencing_object_name = o.name, 
referencing_object_type_desc = o.type_desc 
FROM sys.sql_expression_dependencies se 
INNER JOIN sys.objects o 
ON se.referencing_id = o.[object_id] 
WHERE referenced_entity_name = 'Person' AND o.type_desc = 'View' 

为避免“手动”工作，您还可以使用ApexSQL Clean，这是一个可以查找所有内部和外部依赖关系的SQL Server工具。在结果窗格中选择一个对象，并看到取决于所选择的对象上选择的对象依赖于所有对象，对象：

您还可以过滤对象和可视化的依赖关系：

希望这有助于

您可以使用sys-sql_expression_dependencies在SQL-Server> = 2008（R1 +）
注意：这将需要30秒或更长时间。

如果你只想要的意见，取出标+表值函数（ 'FN' 和 'IF'）。

表值函数可以是视图的依赖关系，反之亦然，再加上view/tvf可能依赖于标量函数。
