Someone sent me a SQL query where the GROUP BY clause consisted of the statement: GROUP BY 1.
This must be a typo right? No column is given the alias 1. What could this mean? Am I right to assume that this must be a typo?
It means to group by the first column of your result set regardless of what it’s called. You can do the same with
ORDER BY.
