关于“Working with JSON and Array data in BigQuery”的评价

There are some corrections to be made: In "Recap of STRUCTs", last point: STRUCTs only need to be unpacked only if the whole STRUCT or its field(s) that you want to access is an ARRAY. In "Lab Question: Unpacking ARRAYs with UNNEST( )": instead of "Order the results with the fastest total time first" should say "...with shortest (or smallest) time first" since time cannot be fast or slow - it is short or long (small or large). In "Practice with STRUCTs and ARRAYs" -> "Practice ingesting JSON data" -> step 3 -> File format should be JSONL, not JSON.
