Researching bugs

Blah. I hate researching bugs. Microsoft SSAS (their BI reporting solution that sits on top of SQL Server) has more than it's share of interesting quirks. Most of them have well-publicized workarounds. We hit one this week that doesn't. Basically, we need ordered sets coming in on a select distinct. Oracle (which we use as our underlying data store) used to always order select distincts. But then they started ordering the results by the hash code rather than the actual data element. No problem, there was a hint you could use to get around that. Then, with Oracle 11, that hint stopped working. Not sure how we're going to get around this, but it's brushing up my research skills trolling the web for answers.
