解題說明：
A VARIANT column in Snowflake can store semi-structured data types. This includes:

* D. ARRAY: An array is an ordered list of zero or more values, which can be of any variant-supported data type, including objects or other arrays.
The VARIANT data type is specifically designed to handle semi-structured data like JSON, Avro, ORC, Parquet, or XML, allowing for the storage of nested and complex data structures.

問題 #263
A stream can be created on which Snowflake objects to record data manipulation language(DML) changes?
(Select TWO).

A. Standard tables
B. Standard tables
C. Database
D. Standard views
E. Pipes
F. Schemas

答案：A,B

解題說明：
Snowflake streams are objects that enable users to track changes (inserts, updates, and deletes) to the data in tables, facilitating real-time data processing and integration workflows. Streams can be created on standard tables, capturing DML changes made to these tables so that downstream processes can consume the changes incrementally. This feature supports efficient data ETL, replication, and real-time analytics by providing a mechanism to process only the data that has changed. Note: The correct options should likely include a distinction between " Standard tables " and another object type such as " External tables " rather than repeating " Standard tables " twice.
