Conclusion. We can use the ORDER BY clause to sort and order results and get the sorted resultset from the original resultset. To perform the ordering in an alphabetical manner, we can either skip specifying the type of order as the default type is ascending or can explicitly mention ASC in the order by clause and mention the criteria for orders containing a column that is character-based. Oct 05, 2021 · If you directly query a Struct column in Google BigQuery, the result will contain multiple columns, one for each of the attributes within the BigQuery Structs.
