Here’s a little snippet I authored this morning, before my cup of coffee, to query the CRM SQL database (YourOrg_MSCRM) for a list of web resources in the order of last ModifiedOn:

select ModifiedOn, Name, DisplayName, OrganizationIdName, WebResourceType
from WebResource --table for web resources
where IsCustomizable = 1 -- just for custom web resources
order by ModifiedOn desc
