Find All References to View

问题:

I've got various databases, and what to be sure I am removing something (a view in this case) that is truly orphaned. Is the the correct SQL to be using:

SELECT r.routine_name, 
       r.routine_definition
  FROM INFORMATION_SCHEMA.ROUTINES r
 WHERE r.routine_definition LIKE '%my_view_name%' 

The problem with it is that these references aren't picking up declarations in stored procedures, and I don't know what else.

I found the SO Question I'd remembered, but it's not helping either. This:

SELECT t.*
  FROM SYSCOMMENTS t
 WHERE CHARINDEX('my_view_name', t.text) > 0

...is close. I get the body of the stored procedure that I know is using the view, but I'm having trouble getting the actual procedure name.

回答1:

You have one option only.

select
    object_name(m.object_id), m.*
from
    sys.sql_modules m
where
    m.definition like N'%my_view_name%'

syscomments and INFORMATION_SCHEMA.routines have nvarchar(4000) columns. So if "myViewName" is used at position 3998, it won't be found. syscomments does have multiple lines but ROUTINES truncates.

Your method is not fully correct. Read this article:

http://www.mssqltips.com/tip.asp?tip=1294

Your method will not return any result if another view uses this view.

SQL Server 2008 has special view (sys.dm_sql_referencing_entities), here it is not that easy.

I am not sure but i guess you can use something like this if your view is used in some stored procedure

SELECT *  
FROM syscomments c  
INNER JOIN sysobjects o ON c.id =o.id 
WHERE text LIKE '%my_view_name%' AND xtype ='p'
