In Snowflake's object hierarchy, a database serves as a primary organizational unit. It acts as a logical container for schemas. Each schema, in turn, contains other database objects such as tables, views, stored procedures, and user-defined functions. This hierarchical structure allows for the logical grouping and management of related data and objects within a single, overarching container. All objects within a database share a common access control framework.
A. Schema: A schema is a container for objects like tables and views, but it is contained within a database, not the other way around.
B. View: A view is a database object that represents a saved query; it does not contain other objects.
C. Table: A table is a fundamental database object that stores data in rows and columns; it does not contain other objects.

Snowflake Notebooks allow for seamless integration between Python and SQL cells. To use a Python variable within a SQL query, you can use a placeholder syntax. This is done by prefixing the Python variable name with a colon (e.g., SELECT FROM mytable WHERE id = :mypythonvariable;). Snowflake automatically substitutes the placeholder with the variable's value at runtime.
A: Manually editing data files is a data manipulation task and is not a method for programmatic variable substitution in code.
B: Network settings are related to connectivity and security, not the logic of variable substitution within a notebook.
D: HTML is a markup language for structuring web pages and has no role in passing variables to SQL queries.

Snowflake’s recommended method for bulk-loading structured data from an internal or external stage into a table is the COPY INTO
