Answer: COPY

The COPY command is specifically designed for loading data from files in external stages into Snowflake tables. According to Snowflake documentation and the community consensus (100% agreement with upvoted comments), COPY is the optimal command for this purpose. INSERT is used for adding individual rows or explicit values, not for bulk loading from external stages. PUT is for uploading files to stages, and GET is for downloading files from stages to local systems. The community discussion clearly supports COPY as the correct answer, with references to official documentation confirming this is the proper command for loading data from external stages into tables.
