我如何检查sql server的“视图”依赖项

Question

有没有办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

您可以使用sys.dm_sql_referenced_entities函数查找指定视图引用的对象：

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

此外，还有sys.sql_expression_dependencies系统视图，您可以在其中指定表名和引用对象的类型：

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'

避免＆＃34;手册＆＃34;你还可以使用ApexSQL Clean这个SQL Server工具来查找所有内部和外部依赖项。在结果窗格中选择一个对象，然后查看依赖于所选对象的所有对象，以及所选对象所依赖的对象：

您还可以过滤对象并可视化依赖关系：

Answer 2

您可以使用sql_dependencies视图：

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

以递归方式检索依赖项（例如，如果从视图中选择，则会找到其他视图引用的表）：

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

这种方法不是万无一失的。例如，如果使用sp_rename重命名对象，则不会更新其依赖项。

这是一个很好的解释：

Answer 4

如果这是你经常做的事情，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，我认为他们有试用期。

Answer 5

您可以使用SQL-Server＆gt; = 2008（R1 +）中的sys.sql_expression_dependencies执行此操作
注意：这将需要30秒或更长时间。

如果仅想要观看，删除标量+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，加上视图/ tvf可能依赖于标量函数。
