Mucking about with SQL strings, to me, is akin to writing your own crypto: Don't. Unless you must (because, say, it doesn't exist yet.) Doing this is asking for security problems later.

And if that interface isn't correct, don't just run off an make your own- contribute a fix so we can keep all the lessons learned together.
