The GROUP BY clause is a venerable member of the SQL statement family. After learning basic SELECT statements, it is one of first specialized parts of SQL that many practitioners cut their teeth on when learning to create aggregations from raw data and transform that data into useful information. These keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
