From what stage can a Snowflake user omit the FROM clause while loading data into a table?
Correct Answer: B
In Snowflake, when loading data into a table using the COPY INTO command, the FROM clause can be omitted if loading from the table's stage, also known as the table stage. The table stage is a default location associated with each table where files can be temporarily stored for loading operations. This simplifies the data loading process by allowing direct loading from files that have been uploaded to the table's stage without specifying the stage explicitly in the COPY INTO command.

Question 357
How often are encryption keys automatically rotated by Snowflake?
Correct Answer: C
Question 358
Which process does Snowflake follow when a stored procedure with owner's rights is called within a session?
Correct Answer: A
* 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. References: * Stored Procedure Privileges Documentation
Question 359
What are valid sub-clauses to the OVER clause for a window function? (Select TWO).
Correct Answer: C,D
Valid sub-clauses to the OVER clause for a window function in SQL are: * C. ORDER BY: This clause specifies the order in which the rows in a partition are processed by the window function. It is essential for functions that depend on the row order, such as ranking functions. * D. PARTITION BY: This clause divides the result set into partitions to which the window function is applied. Each partition is processed independently of other partitions, making it crucial for functions that compute values across sets of rows that share common characteristics. These clauses are fundamental to defining the scope and order of data over which the window function operates, enabling complex analytical computations within SQL queries.

Question 360
Which function returns an integer between 0 and 100 when used to calculate the similarity of two strings?
Correct Answer: B
TheJAROWINKLER_SIMILARITYfunction in Snowflake returns an integer between 0 and 100, indicating the similarity of two strings based on the Jaro-Winkler similarity algorithm. This function is useful for comparing strings and determining how closely they match each other. Understanding JAROWINKLER_SIMILARITY:The Jaro-Winkler similarity metric is a measure of similarity between two strings. The score is a number between 0 and 100, where 100 indicates an exact match and lower scores indicate less similarity. Usage Example:To compare two strings and get their similarity score, you can use: SELECTJAROWINKLER_SIMILARITY('string1','string2')ASsimilarity_score; Application Scenarios:This function is particularly useful in data cleaning, matching, and deduplication tasks where you need to identify similar but not identical strings, such as names, addresses, or product titles.
