Answer choices
Why each option matters

Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Nested subqueries.
Why it's wrong here
Subqueries can be difficult to read and manage in complex logic.
- ✓
WITH clause (CTE).
Why this is correct
CTEs are standard, readable, and well-optimized by BigQuery.
- ✗
Variable declaration.
Why it's wrong here
BigQuery standard SQL does not support temporary variable tables in the same way as procedural SQL.
- ✗
CREATE TABLE AS SELECT.
Why it's wrong here
This creates a physical table, which is slow and requires cleanup.
