A user has 10 files in a stage containing new customer data. The ingest operation completes with no errors using the following command: ```sql COPY INTO my_table FROM @my_stage; ``` The next day, the user adds 10 more files to the stage, which now contains a mixture of new customer data and updates to the previous data.
