How many of each event

SQLAlgorithms & data structuresEntry~7 min

Count how many times each event name occurs. Return `name` and `times`, most frequent first, then alphabetically.

What a strong answer looks like

Say what the query is meant to return before you write it, and name the shape of the answer: how many rows, grouped by what. Then watch the NULLs and the duplicates, because that is where most of these are lost.

Run onlyA query runs as one statement, so there is nothing to step through. Run it and read the rows.
