QUESTION: 113

Which data types does Snowflake support when querying semi-structured data? (Select TWO)

VARIANT
ARRAY
VARCHAR
XML
BLOB

Answer(s): A,B

Explanation:

A VARIANT stores semi-structured data in Snowflake. It can store a value of any other type, including OBJECT and ARRAY.
The maximum length of a VARIANT is 16 MB.
A Snowflake ARRAY is similar to an array in many other programming languages. An ARRAY contains 0 or more pieces of data. Each element is accessed by specifying its position in the array.

QUESTION: 115

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?

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

Answer(s): B

Explanation:

Data Size Limitations
The VARIANT data type imposes a 16 MB size limit on individual rows.

For some semi-structured data formats (e.g. JSON), data sets are frequently a simple concatenation of multiple documents. The JSON output from some software is composed of a single huge array containing multiple records. There is no need to separate the documents with line breaks or commas, though both are supported.
If the data exceeds 16 MB, enable the STRIP_OUTER_ARRAY file format option for the COPY INTO
<table> command to remove the outer array structure and load the records into separate table rows:

copy into <table>
from @~/<file>.json
file_format = (type = 'JSON' strip_outer_array = true);
