... So in my attempts to navigate the ESRI, ARCGIS website to post a question... it has led me to this point... so... hopefully this would be the place to ask a simple question.... I feel lost and confused...
I have attachment data posted in ArcGIS online, but due to a misunderstanding of the MAX TABLE RETURN when publishing content, i'm limited to downloading 1000 records...... So one path i'm looking into in order to get to my data down and republish... i will need to download it in 1000 feature chunks using "Create local copy for editing". (Note that i have over 9000 points and 4 GB worth of attachment data... up in the cloud)
So now i have 8 databases, each with an attachment table, identical schema and assumed global IDs that were generated when publishing to AGO. How might one merge these attachment tables and maintain the relationship into a single MASTER dataset?
Getting the feature classes together seems is a simple enough task but i assume it can't be as easy as "loading data" into the attachment table? THere was a help doc related to restoring relationship table... but really lookin for guidance . Also i would use the Export to file geodatabase option that was recently added with the July AGO release but unfortunately, it fails due to the fact that i don' think they were expecting someone to host over 5 GB worth of attachment data
What is the easiest way to merge data together into a single attachment table and dataset?
The Global IDs are unique - so you should not end up with duplicates, as opposed to where you probably would with ObjectIDs. If the data was hosted on AGOL the features would have automatically been assigned Global IDs. But if you are working with data that does not have Global IDs and need them, you can add them at the Feature Dataset level.
Thanks to Jessica for the methodology document. Just wanted to share my tweaked method that retains a GlobalID relationship. This way it can go right back up to AGO or SDE.
**Note GUID fields do not seem to work well in Personal Geodatabases. For this purpose use a File GDB
Thanks, Just wanted to pay some help forward even if I am 2 years late.
This was incredibly helpful!
I had four GDBs on AGOL with attachments collected in the field. I needed to get these GDBs into a enterprise GDB in-house. I was able to download from AGOL, and then load into our in-house enterprise GDB, and retain the attachments.
One thing I did slightly differently. I created an empty schema on our enterprise database, and used the object data loader added into the editor tool bar to load the feature points (and retained the original GLOBALID in a new field) . Then I essentially followed the steps above for the attachment table.
