C++03 and earlier stipulate that literal 0 is always the null pointer, whether it really is on any given hardware or not. C++11 and later deprecate this and introduce a new keyword `nullptr`. edit: Also, null is not an empty string. The null character that terminates a string is unrelated to null pointers.

In Oracle SQL, an empty string is equivalent to a null, as I recall. However, that is not true for all databases.

Normally I call it the NUL character to distinguish it.
