It requires a  _blob_column=  query string argument specifying which BLOB column should be downloaded, for example: \n             https://latest.datasette.io/fixtures/binary_data/1.blob?_blob_column=data \n             This output format can also be used to return binary data from an arbitrary SQL query. Since such queries do not specify an exact row, an additional  ?_blob_hash=  parameter can be used to specify the SHA-256 hash of the value that is being linked to. \n             Consider the query  select data from binary_data  -  demonstrated here . \n             That page links to the binary value downloads.
