ORMs make 95% of queries/tasks simpler, but when you encounter the other 5% the lack of "practice" regarding how the database works under the hood will bite you

ORMs make 95% of queries/tasks simpler, but when you encounter the other 5% the lack of "practice" regarding how the database works under the hood will bite you in the ass. Somehow I became the "database guy" of my workplace (small startup without a dedicated DBA) and everybody thinks I really dislike our ORM because all they hear me say about it is pretty negative. However, that is because nobody comes to me with the 95% of easy questions so every question I get is one of the 5% edge cases where the ORM is really not a good fit :|
