質問 # 157
A user is loading JSON documents composed of a huge array containing multiple records into Snowflake.
The user enables the strip__outer_array file format option
What does the STRIP_OUTER_ARRAY file format do?

A. It removes the last element of the outer array.
B. It removes the outer array structure and loads the records into separate table rows,
C. It removes the NULL elements from the JSON object eliminating invalid data and enables the ability to load the records
D. It removes the trailing spaces in the last element of the outer array and loads the records into separate table columns

正解：B

解説：
The STRIP_OUTER_ARRAY file format option in Snowflake is used when loading JSON documents that are composed of a large array containing multiple records. When this option is enabled, it removes the outer array structure, which allows each record within the array to be loaded as a separate row in the table. This is particularly useful for efficiently loading JSON data that is structured as an array of records1.

質問 # 158
How can the outer array structure of a semi-structured file be removed?

A. Filter the outer array structure using a PUT command with the include_outer_array = false parameter.
B. Use the FLATTEN command with the outer_array = false parameter.
C. Use the parameter strip_outer_array = true in a COPY INTO <table> command.
D. Set the file format to eliminate any outer array structure before initiating the COPY INTO <table> command.

正解：C

解説：
In Snowflake, the parameter strip_outer_array = true can be set in the COPY INTO <table> command to remove the outer array structure from a semi-structured file. This parameter is useful for JSON files or similar data formats where an array might wrap the data, allowing Snowflake to directly load the inner elements as table rows.
