Who? I've done so many "can you write a query that gives me all the foo bars where so an so" for managers, cs people, or even data analysts, that it makes my skin crawl. Sometime they know how to load that data into Excel and do their magic there, but with SQL, anything that's more complicated than a simple select from a single table, forget about it.
I have designed/given internal SQL classes to business analysts, product managers and similar.
From simple selects using some common functions and basic types, to filtering, to aggregations and grouping and finally joins. That gets them about 80% there for the kind of information they want ad-hoc.
Only with joins did the people really struggle for some time.
In my opinion the distinguishing factor wasn't the language, but the peoples willingness to learn and ability to apply it in practice on a somewhat regular basis.
