Exam DEA-C02 Topic 1 Question 38 Discussion

Actual exam question for Snowflake's DEA-C02 exam
Question #: 38
Topic #: 1
You have a Snowflake table 'orders_raw' with a VARIANT column named 'order detailS that contains an array of order items represented as JSON objects. Each object has 'item id', 'quantity' , and 'price'. You need to calculate the total revenue for each order. Which SQL statement efficiently flattens the array and calculates the total revenue using LATERAL FLATTEN and appropriate casting?

Suggested Answer: E Vote an answer

Option E is the most efficient and correct. It uses 'LATERAL FLATTEN' to unnest the 'order_details' array. It then casts both the quantity' and 'price' fields to FLOAT, ensuring accurate calculations for total revenue. A, B and D are incorrect due to incorrect join syntax or function usage with lateral flatten, or improper datatypes. C doesn't properly flatten the array so it only accesses the first element.
