Answer: PUT

The PUT command is specifically designed to upload data files from a local file system on a client machine to Snowflake internal stages, including named internal stages, table stages, and user stages. According to the Snowflake documentation referenced in the community discussion, PUT supports uploading to a specified table's internal stage, which directly matches the question requirement. Option A (GET) is for downloading files from stages, not uploading. Option C (CREATE STREAM) is for creating stream objects for change data capture, not file uploads. Option D (COPY INTO) is for loading data from stages into tables, not uploading files to stages. The community discussion shows 100% consensus on B with supporting documentation evidence.
