Worksheets in Snowsight can be shared directly with other Snowflake users within the same account. This feature allows for collaboration and sharing of SQL queries or Python code, as well as other data manipulation tasks1.

To upload data files from a local directory or folder on a client machine to an internal stage in Snowflake, thePUTcommand is used. ThePUTcommand takes files from the local file system and uploads them to an internal Snowflake stage (or a specified stage) for the purpose of preparing the data to be loaded into Snowflake tables.
Syntax Example:
PUT file:// < local_file_path > @ < stage_name > ;
This command is crucial for data ingestion workflows in Snowflake, especially when preparing to load data using theCOPY INTOcommand.

The GET_PRESIGNED_URL function in Snowflake generates a presigned URL for a file stored in an internal stage, allowing direct access to the file without requiring Snowflake access. This feature is particularly useful for sharing unstructured data with external applications or tools that do not have direct access to Snowflake. The presigned URL provides temporary access to the file, making it an ideal solution for securely sharing unstructured data from an internal stage with a reporting tool or any other external application.
