I have a Firebird database with blob subtype=0 (binary) storing picture/image data. I use fdb driver in Python to query the image data using set_stream_blob() and fdb.fbcore.BlobReader() function. I cannot find a way to store it back to Firebird if I update the data.
I get error:
Unicode strings are not acceptable input for non-textual BLOB column.
Please advise what the command is to update it.
