Basically, in Oracle, you can’t say things like

    SELECT NOW();

because a SELECT without a `FROM` clause is a syntax error. So
instead it has this weird special-case single-row, single-column
table called `dual` that always exists, so you have to say things
like that like so:

    SELECT SYSDATE FROM dual;

Isn’t Oracle cool?
