In Paradigm4/SciDBR: An R Interface to SciDB

Common function called by all upload methods. Upload bytes or text to SciDB as an attachment to a query. The query must contain an input() or aio_input() operator that reads data from the attached file (whose name matches desc@filename) and does something with it; usually, the query uses store() to write the data into a new array.

Description

Common function called by all upload methods. Upload bytes or text to SciDB as an attachment to a query. The query must contain an input() or aio_input() operator that reads data from the attached file (whose name matches desc@filename) and does something with it; usually, the query uses store() to write the data into a new array.

Usage

.UploadWithQuery.httpapi(db, data, query, schema, content_type, desc)

Arguments

db	scidb database connection returned from scidbconnect
data	the data to upload, as text or raw bytes
query	an AFL query to process the uploaded data (and, usually, to store it into an array). The query must contain an operator that reads from a file whose name is equal to desc@filename.
schema	the schema of the array, only needed if desc@temp is TRUE
content_type	the HTTP Content-Type header to use for the attachment
desc	an UploadDesc which must have an @array_name and @filename set

Value

if the query returns data, this function returns the raw data from the HTTP response. If the query doesn't return anything (e.g. if it's a store() query), this function returns NULL. If the server returns any status code outside of the 200 successful range, this function stops with a message that includes the content of the error page returned by the server.
