Is it possible with a Stored Procedure to upload a file?

I want to replace this by a Stored Procedure function:

curl -X 'POST' \ 'https://dev.somesite/api-external/stock/import-file' \

-H 'accept: application/json' \

-H 'authorization: Basic dHN....==' \

-H 'Content-Type: multipart/form-data' \

-F 'File=@myfile.csv;type=application/'

My Stored Procedure:

ALTER PROCEDURE "DBA"."sp_tsd_catalogus_toc"(IN "file" NTEXT)

result( "Attribute" long NVARCHAR,"Values" long NVARCHAR, instance INTEGER )

url ''

type 'HTTP:POST'

header 'accept:application/json\nauthorization: Basic dHNk...==\ncontent-Type:multipart/form-data'

With this I got a 400 error. I think because the in parameter 'file' contains the content of the file. Is it possible to save a file at the serverside and post that filename in de SP?

Anybody an idea?

I would generally use the "web client debug feature" (aka the -zoc database server option or via "CALL sa_server_option('WebClientLogging', 'On')") to check the request sent to the web server.

We upload documents in the database

CREATE SERVICE rawUploadDocument
TYPE 'raw' 
CALL UploadDocument(HTTP_BODY())

In this procedure in the end we store the file on disc

 set l_FullFilename = 'c:\images\word\'\|| Description ||'.'|| Extension
 select xp_write_file(l_FullFilename,BASE64_DECODE(Image))

We use Json to send the image base 64 encoded

{"extension": "docx"
 "Description": "Quote for customer xxxxxx"
 "Image": "....." -- Image Base64 encoded

I hope this wil help

I asked the API developer to modify there API to accept the content of the file, instead of a file upload. So the problem is 'solved', I can upload my data with SA17 now.
