Where Dynamics CRM IsLogical attributes are stored?

Question

I want to know where the IsLogical attributes are stored? for example:- if the user creates an image attribute, the system will create three attributes(imageId, Image Url, image timestamp); the image id is stored on the table but i don't know where the other attributes are stored; Image Attribute

Answer 1

Image information is stored in the ImageDescriptor table which you can access from the FilteredImageDescriptor view.

The filtered view contains the fields (among others):

• imagedescriptorid (the GUID linked from your source table)
• imagetimestamp
• objectid
• objecttypecode (source entity type code)
• imageurl (concatenated URL, relative to the CRM root)

However, if you use the filtered view of your custom entity (for example Filterednew_mycustom) which contains an image field, the filtered view will automatically bring in the fields:

• entityimage
• entityimage_timestamp
• entityimage_url
• entityimageid
