Message Senders Without Voice Joins

EasySQL · PostgreSQL

Problem

You are given a Discord-style event log that records user actions across surfaces such as text chat and voice. Write a SQL query to return the users who have sent at least one message but have never joined a voice channel.

Use only the user_interactions table. Your result should include each qualifying user_id, the number of message events they generated, and be ordered by message count descending and then user_id ascending.
