A data analyst has a VARIANT column named payload that contains a JSON object. The analyst needs to add a new key-value pair 'status' with value 'active' to the object, without modifying the original data. Which function should the analyst use?

OBJECT_INSERT(payload, 'status', 'active')

ARRAY_APPEND(payload, 'status', 'active')

OBJECT_CONSTRUCT(payload, 'status', 'active')

TO_JSON(payload) || ',"status":"active"'

In a Snowflake FLATTEN function call, what does the KEY column contain?

The sequence number of the original row

The index of the element in an array, or NULL for object data

The path to the element within the nested structure

The key for object data, or NULL for array data

When using the FLATTEN function in Snowflake, which of the following correctly describes the purpose of the THIS column in the output?

It contains the value of the current element being processed.

It specifies the path to the parent element in the hierarchy.

It indicates the index position of the current element in the array.

It stores the original key name for each key-value pair in an object.
