For version 2008 or greater check the following catalog views in BOL:

- sys.sql_expression_dependencies

- sys.dm_sql_referencing_entities

- sys.dm_sql_referenced_entities

Hi

I found this in my repository

select 'TO', 'Object name' = (s6.name+ '.' + o1.name),

[Type] = substring(v2.name, 5, 16),

[Updated] = substring(u4.name, 1, 7),

[Selected] = substring(w5.name, 1, 8),

'Column' = col_name(d3.depid, d3.depnumber)

from sysobjects o1

,master.dbo.spt_values v2

,sysdepends d3

,master.dbo.spt_values u4

,master.dbo.spt_values w5

,sysusers s6

where o1.id = d3.depid

and o1.xtype = substring(v2.name,1,2) collate database_default and v2.type = 'O9T'

and u4.type = 'B' and u4.number = d3.resultobj

and w5.type = 'B' and w5.number = d3.readobj|d3.selall

and d3.id = OBJECT_ID('schema.your_sp_name')

and o1.uid = s6.uid

and deptype < 2

this seems to work for me;

I had this saved in my snippets:

SELECT depz.referenced_schema_name,

depz.referenced_entity_name,

objz.type_desc,

depz.referencing_id,

Object_schema_name(depz.referencing_id),

Object_name(depz.referencing_id),

colz.name AS ColumnName

FROM sys.sql_expression_dependencies depz

INNER JOIN sys.objects objz

ON depz.referencing_id = objz.object_id

LEFT OUTER JOIN sys.columns colz

ON objz.object_id = colz.object_id

AND colz.column_id = referencing_minor_id

WHERE referenced_id = Object_id(N'EDLogDetail');

--AND colz.name = 'EmployeeNumber'

I may be remembering incorrectly, but if you use dynamic SQL in your procedures, the dependency might not show up in the list. If you find that's the case, something like this will help you find those references.

select object_schema_name(object_id), object_name(object_id), definition

from sys.sql_modules

where definition like '%EDLogDetail%'

order by object_schema_name(object_id), object_name(object_id);

good point Ed;

even that might not catch 100%, if some dynamic SQL was getting a tablename from say, sys.tables or from a paramters, and executing a command built from that.

SET @cmd = 'SELECT TOP ' + CONVERT(VARCHAR,@Top) + ' * FROM ' + QUOTENAME(@TblName) + ' ORDER BY 1 DESC '

EXEC(@cmd)

also , because of late binding, it's possible to create a procedure that references a table that doesnt exist at the time of procedure creation(yet);

in that case there's no references in the views unless you ALTER PROC and rebuild it with the same definition.

i try to check for invalid objects and rebuild just in case as well.
