For those who like SQLite, it allows you to create tables and columns with zero length names (you have to quote) and it does indeed work correctly when you use them. This is valid:
CREATE TABLE ""("" "");
A zero length table name with one column with a zero length name having a type of a zero length name.
CREATE TABLE ""("" "");
A zero length table name with one column with a zero length name having a type of a zero length name.
