Write Blob field via Python?

LewLadd — Tue, 13 Sep 2011 22:45:11 GMT

Hi Guys,
I have a feature class with a blob field designed to hold images uploaded by users.

Is it possible to populate the blob field via a python based service?
Thanks,
Lew.

Hmmm... Just found this post which says "ArcPy doesn't support reading or writing blob fields at 10.0."

I have never used a blob field before (so I'm not sure if it can do other fancy stuff as well), but can you store the file path as a string? You can definitely do that in Python - check out UpdateCursor.

Hi Stacy,

    Thanks for taking the time to reply.

    I wrote a quick test and trying to update with:

      newRow["myBlob"] = someBlob

does fail as you predicted.

So I'm using a column 'blobPath' and writing the blob to the path via a C# based fileUploader.

Thanks again,
Lew.
