NEW QUESTION # 14
Which Snowflake feature allows users to encapsulate a series of SQL statements into a reusable database object, facilitating modular code development?
Answer: D
Explanation:
In Snowflake, a Stored Procedure is the primary object used for procedural logic and the encapsulation of multiple SQL statements. Unlike standard functions that are typically restricted to returning a single value or a table based on an input, Stored Procedures are designed to perform administrative tasks, wrap complex business logic, and execute a sequence of operations-such as DDL (Data Definition Language) and DML (Data Manipulation Language) commands-within a single callable object.
Modular code development is facilitated by Stored Procedures because they allow analysts and developers to write logic once and reuse it across various workflows. For example, a procedure can be written to truncate a staging table, call a COPY INTO command, and then execute several INSERT statements into a final fact table. This "wrapper" approach ensures consistency, as any change to the logic only needs to be updated in the procedure definition rather than in every script or task that uses it.
Evaluating the Options:
* Option B is incorrect because a Materialized View is a pre-computed result set used to improve query performance; it does not "encapsulate a series of statements" for procedural execution.
* Option C is incorrect because while User-Defined Functions (UDFs) provide reusability, they are generally intended for calculations or data transformations that return a result. They are much more restricted than procedures; for instance, a UDF cannot execute DDL commands like CREATE TABLE.
* Option D is incorrect because a Common Table Expression (CTE) is a temporary named result set defined within the execution scope of a single SELECT, INSERT, UPDATE, or DELETE statement. It is not a persistent database object and cannot be reused across different sessions or scripts.
* Option A is the correct answer. Snowflake Stored Procedures can be written in multiple languages (JavaScript, Snowflake Scripting/SQL, Python, Java, or Scala), providing the flexibility needed for sophisticated, modular automation in a data pipeline.
NEW QUESTION # 15
A Data Analyst created a SQL statement that updates a table used for reporting. The Analyst now wants to automate the execution of that SQL.
The Analyst decides to use a task for this along with a stream called MYSTREAM on the source table so only they can update the table if there is new data.
Which statement will create a task that will execute when there is new data in MYSTREAM without having to be executed manually?
Answer: D
Explanation:
To automate a data pipeline in Snowflake using Tasks and Streams, an analyst must understand the relationship between scheduling and conditional execution. A task is an object used to execute a single SQL statement (or a call to a stored procedure) on a recurring basis. A stream, on the other hand, tracks Change Data Capture (CDC) metadata for a table, indicating whether new rows have been added, updated, or deleted.
The core requirement of this question is to ensure the task runs automatically but only if there is new data. In Snowflake, a task requires a SCHEDULE parameter to run automatically without manual intervention. The SCHEDULE defines the frequency (e.g., '5 MINUTE' or a CRON expression) at which the task "attempts" to run. However, to prevent wasting credits by running the task when no data has changed, the WHEN clause is used in conjunction with the system function SYSTEM$STREAM_HAS_DATA('stream_name').
Evaluating the Options based on the exhibit (image_8c9a13.png):
Option A is incorrect because it lacks a SCHEDULE. Without a schedule, the task is considered "standalone" and will never execute unless manually triggered by an EXECUTE TASK command.
Option B is incorrect because it incorrectly attempts to place the SYSTEM$STREAM_HAS_DATA function within the SCHEDULE parameter. The schedule must be a time-based interval or a cron string.
Option C is incorrect because 'STREAM' is not a valid schedule interval.
Option D is the 100% correct answer. It provides a valid time-based SCHEDULE ('2 minute') which enables the task to heart-beat automatically. It then correctly utilizes the WHEN clause with SYSTEM$STREAM_HAS_DATA('MYSTREAM'). This configuration ensures that every two minutes, Snowflake checks the stream; if the stream contains data, the task executes the SQL; if the stream is empty, the task skips the execution, saving compute resources. This pattern is the industry standard for building efficient, automated Data Transformation pipelines in the Snowflake Data Cloud.
NEW QUESTION # 16
A company ingests sensor data into a Snowflake table named READINGS with columns (VARCHAR), 'reading_time' (TIMESTAMP NTZ), and 'raw_value' (VARCHAR). The 'raw_value' column contains numeric data represented as strings, but sometimes includes non-numeric characters (e.g., '123.45', 'N/A', '500'). You need to calculate the average of the numeric raw_value' readings for each within the last hour, excluding invalid readings. Which of the following Snowflake SQL statements will correctly accomplish this, handling potential conversion errors and filtering for valid data?
Answer: B
Explanation:
Option B is the correct answer because 'TRY TO NUMBER attempts to convert the 'raw_value' to a number, returning NULL if the conversion fails. The 'AND TRY_TO_NUMBER(raw_value) IS NOT NULL' clause then filters out these NULL values, ensuring only valid numeric readings are included in the average calculation. Option A will throw an error if it encounters a non-numeric value. Option C, while functionally correct, utilizes which can be less reliable for specific locale formats compared to Option D is unnecessarily complex and less readable. Option E only handles 'N/A', not other potential invalid values.
NEW QUESTION # 17
You are working with a table 'ORDERS' containing order data, and a table 'CUSTOMER SEGMENTS containing customer segment information. The 'ORDERS' table has columns 'ORDER ID', 'CUSTOMER ID, and 'ORDER AMOUNT'. The 'CUSTOMER SEGMENTS' table has columns 'CUSTOMER ID', 'SEGMENT ID', and 'SEGMENT NAME'. You need to create a query that enriches the 'ORDERS' table with the customer segment information. However, a customer can belong to multiple segments. You want to include all segments a customer belongs to in the enriched data, resulting in potentially multiple rows per order if the customer is in multiple segments. The output should include 'ORDER ID, 'ORDER AMOUNT, 'SEGMENT ID', and 'SEGMENT NAMES. Which SQL statement would correctly enrich the ORDERS table without losing any order information, even if customers belong to multiple segments?
Answer: A
Explanation:
An 'INNER JOIN' is the correct choice here. It will return all matching rows between the 'ORDERS' and tables based on the 'CUSTOMER ID. If a customer belongs to multiple segments, each segment will be returned in a separate row associated with the order. "LEFT JOIN' includes rows from the left table even without a match in the right table which is not needed. 'GROUP BY' in the INNER JOIN' will combine multiple segments with 'ORDER_IDS into one row, which is not needed as all segment names are expected. The subquery approach would only return one segment name per order. 'RIGHT JOIN' include all customer segments on the right which is also not needed.
NEW QUESTION # 18
How can automated and repeatable tasks contribute to maintaining reports and dashboards to meet business requirements?
