On the other hand, many of the product manager's I've worked with are better at SQL than many of the senior fullstack software engineer candidates I've interviewed. It's a strange world out there.
On the other hand, sql is also dangerous in that it gives you a result, even if the aggregation is completely wrong! Forgetting empty groups in a group by, loosing rows in a join or ignoring null values is common to see. Many cases of non techies “knowing” sql often turn out to be some basic query that give seemingly good data out but actually is complete nonsense when put under deeper review, a bit like AI hallucinations.
But you’re right, many of them are wizards in <whatever query language our tool uses>. Like VizQL for Tableau.
