I forgot to add a MATCH_RECOGNIZE solution to my last post on merging overlapping date ranges! That should take me just a few minutes, right? Wrong: it’s not that easy and here’s why. For test data, please refer to the previous post. To Merge or not to Merge? The idea is to merge date ranges if […]
