An empty string is just a string, so unless drivers actively test for it,  that should work I guess. 
But this is certainly playing a bit with fire. Wouldn't be surprised that applications consuming 
such empty field name don't like it much.

Actually just seeing that PostgreSQL and mySQL don't like empty string as a column. It seems 
to be a general SQL92 restriction actually (SQLite3 is an exception to that)
