an example of checkign the references HanShi mentioned:

--Objects:

SELECT objz.name,

fn.*

FROM sys.objects objz

CROSS APPLY sys.dm_sql_referenced_entities(schema_name(schema_id) + '.' + objz.name,'OBJECT')fn

WHERE referenced_entity_name ='all_data'

and just in case, you can check the definitions of all objects as well:

select OBJECT_NAME(object_id) As ReferencingObject, *

from sys.sql_modules

where definition like '%all_data%'
