The Snowflake PUT command is used to upload files from a local file system to Snowflake stages, specifically the user stage, table stage, and internal named stage. These stages are where the data files are temporarily stored before being loaded into Snowflake tables

* Owner's Rights Stored Procedures:
* When a stored procedure with owner's rights is called, it runs with the privileges of the owner, not the caller.
* This ensures that the procedure executes with access to objects the owner has privileges for, regardless of the caller's permissions.
Why Other Options Are Incorrect:
* B. The owner can set the caller's session variables: Stored procedures cannot modify session variables of the caller.
* C. The owner will inherit the caller's current virtual warehouse: The procedure uses the session's current warehouse, not inherited settings.
* D. The owner can view the caller's session variables: Session variables are private to the caller and not visible to the owner.

* A stream in Snowflake tracks changes (e.g., inserts, updates, and deletes) to a table. Its offset advances only when the stream is consumed or re-created.
* CREATE OR REPLACE STREAM triggers the stream to reset its offset, effectively advancing it by overwriting the existing stream definition.
* Other operations like querying the stream (SELECT) or applying changes (INSERT) would also advance offsets, but only CREATE OR REPLACE affects the offset in this context.
Why Other Options Are Incorrect:
* A. DESCRIBE STREAM: Does not affect the stream offset; it only retrieves metadata.
* B. ALTER STREAM: Modifies the stream properties but does not advance the offset.
* C. DROP STREAM: Deletes the stream but does not advance its offset.

* To unload data into an external named stage, the command COPY INTO <location> is used.
* Example Syntax:
sql
CopyEdit
COPY INTO 's3://mybucket/mypath/'
FROM my_table
STORAGE_INTEGRATION = my_s3_integration;
* This command exports data from Snowflake tables into external storage like AWS S3, Azure Blob Storage, or Google Cloud Storage.

Column-level security in Snowflake is implemented through Role Access Policies. These policies allow administrators to control access to specific columns of a table or view based on the role of the user accessing the data. By applying a role access policy to a column, administrators can ensure that sensitive information remains secure, and only users with the appropriate roles can view or query the data in that column. This feature enhances the security model by providing fine-grained access control at the column level.
