"compose relational queries dynamically"

That's an important one. It would be super nice to have a SQL dialect that works more like LINQ where you can compose your queries easily. I always hate it when I have to write SQL directly. It's super powerful but the syntax just isn't designed well. To me it feels like a throwback to the good old FORTRAN or COBOL days: you can get stuff done but modern languages are so much better.
