I had some trouble with doctrine DBAL, mostly with the schema/database/table creation, it was buggy and some of documentation was different from actual interfaces and class methods(I did read right version documentation), I had to use raw sql statements for some of those things.
Everything else seemed to be fine, it was small project so I did not use all the features doctrine DBAL provides.
Note:
I did it around a year ago with latest stable version of doctrine DBAL and php, maybe all those problems are fixed by now.
