Does anybody have a recommendation for a decent read-heavy/only "OLTP-ish" database benchmark where the queries aren't just single-table point or range selects?

Would like to showcase some scalability problems + solution that I see with such queries, but right now it's mostly visible with queries I made up on my own. It's easy enough to make up workloads that show almost anything, so I'd rather use something designed by someone else.
