I have an SDE database that is running on sql server. I have a feature class of polygons with attachments enabled. This means there is an attachments table in sql. Is it possible to mass upload attachments to this table based off of a table of attachments with a unique ID of the polygons?
You can use these GP tools; Add Attachments—Help | ArcGIS Desktop and a match table; Generate Attachment Match Table—Help | ArcGIS Desktop
This should work.
