In reality, though, I think portability between databases is more hypothetical than real. Projects typically start with one database and stick to it, for moving between databases *even if a portability layer is in use* turns out to be hard -- all sorts of stuff outside the main code base ends up changing (path names, load scripts, whatever).
Yeah, but finer-grained things than apps can be portable. Eg, OR mapping layers. Being general-purpose tools, they want to be able to work on lots of different SQL servers, so the authors of them often avoid server-specific SQL, and where they have to for efficiency or whatever, make a decision what syntax to use there and then in that one place. So they benefit from a generic interface for the bulk of their queries.
