To change a Standard virtual warehouse to a Snowpark-optimized virtual warehouse, the warehouse must be in a suspended state. This ensures that no operations are disrupted during the modification process.

Suspend the Warehouse: Ensure that the warehouse is suspended.

ALTER WAREHOUSE my_warehouse SUSPEND;

Alter the Warehouse: Modify the warehouse to be Snowpark-optimized.

ALTER WAREHOUSE my_warehouse SET WAREHOUSE_TYPE = 'SNOWPARK-OPTIMIZED';

Resume the Warehouse: Resume the warehouse to make it operational.

ALTER WAREHOUSE my_warehouse RESUME;

To see the definition of a secure view in Snowflake, the minimum privilege required is OWNERSHIP of the view. Ownership grants the ability to view the definition as well as to modify or drop the view. Secure views are designed to protect sensitive data, and thus the definition of these views is restricted to users with sufficient privileges to ensure data security.

The type of Snowflake table that persists until it is explicitly dropped, is available for all users with relevant privileges across sessions, and does not have a Fail-safe period, is a Transient table. Transient tables are designed to provide temporary storage similar to permanent tables but with some reduced storage costs and without the Fail-safe feature, which provides additional data protection for a period beyond the retention time. Transient tables are useful in scenarios where data needs to be temporarily stored for longer than a session but does not require the robust durability guarantees of permanent tables.

To unload data from a relational table to JSON format, you can use the TO_CHAR function. This function converts a number to a character string, which can then be serialized into JSON format. While there isn't a direct function specifically named for unloading to JSON, converting the necessary fields to a string representation is a common step in preparing data for JSON serialization.
