What is the purpose of using LATERAL FLATTEN in a Snowflake query?

To convert a JSON string to a VARIANT

To join semi-structured data with relational tables in a single query

In a Snowflake SQL query, what is the purpose of the OUTER parameter in the FLATTEN function?

It forces the input to be treated as a single-row array even if it is an object.

It removes duplicate rows that result from flattening multiple paths.

It includes rows for which the input expression produces no rows, filling missing columns with NULL.

It limits the output to only the first level of nested arrays or objects.
