COPY has many parameters that can be used in many situations. However, not all parameters are supported in each situation. For example, to load from ORC or PARQUET files there is a limited number of supported parameters. For more information, see [COPY from columnar data formats](copy-usage_notes-copy-from-columnar.md).
