The correct way to use the COPY command to unload data from a table to an internal stage in Snowflake is to use the syntax `COPY INTO <location>`. This command specifies the target location where the data will be unloaded. The `<location>` denotes a Snowflake stage, which can be internal or external. For internal stages, the command does not need additional specifications like URLs or parameters that are associated with external storage services like S3.
