What does the TableScan operator represent in the Query Profile?
- A. The access to data stored in stage objects
- B. The access to a single table
- C. The records generated using the TABLE (GENERATOR (...)) construct
- D. The list of values provided with the VALUES clause
正解：B
解説：
In the Query Profile of Snowflake, the TableScan operator represents the access to a single table. This operator indicates that the query execution involved reading data from a table stored in Snowflake. TableScan is a fundamental operation in query execution plans, showing how the database engine retrieves data directly from tables as part of processing a query.

質問 # 286
Use of which file function allows a user to share unstructured data from an internal stage with an external reporting tool that does not have access to Snowflake">
- A. BUILD_STAGE_FILE_URL
- B. GET_PRESIGNED_URL
- C. GET_STAGE_LOCATION
- D. BUILD_SCOPED_FILE_URL
正解：B
解説：
The GET_PRESIGNED_URL function in Snowflake generates a pre-signed URL for a file in an internal stage. This URL can be shared with external tools or users who do not have direct access to Snowflake, allowing them to download the file.
* Generate Pre-Signed URL:
SELECT GET_PRESIGNED_URL(@my_stage/file.txt);
* Share the URL: The generated URL can be shared with external users or applications, enabling them to access the file directly.

質問 # 290
Which of the following Snowflake capabilities are available in all Snowflake editions? (Select TWO)
- A. Customer-managed encryption keys through Tri-Secret Secure
- B. Column-level security to apply data masking policies to tables and views
- C. Automatic encryption of all data
- D. Up to 90 days of data recovery through Time Travel

質問 # 294
Which function unloads data from a relational table to JSON?
- A. TRUNC(ID_NUMBER, 5)
- B. TO_CHAR<ID NUMBER)
- C. ID_NUMBER*100
- D. TRUNC<ID_NUMBER, -6)
正解：B
解説：
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.

質問 # 295
Which table function will return the output of a previously-run command?
- A. QUERY_HISTORY
- B. FLATTEN
- C. TASKHISTORY
- D. RESULT_SCAN
正解：D
解説：
* The RESULT_SCAN function returns the output of a previously executed query by referencing its query ID.
* Example:
SELECT * FROM RESULT_SCAN('query_id');
* Other functions like QUERY_HISTORY or TASK_HISTORY provide metadata about queries but do not return query results.
