This method returns TRUE if the field can accept NULL values.
Usage
oboolean IsNullOK(void) const
Remarks
NULL is a possible value for Oracle database fields. This database NULL is
different from a C++ NULL. Database NULLs mean "no value set". Some fields are not
allowed to contain NULLS. This routine tells you whether the indicated field
is allowed to have NULL values.
Return Value
TRUE if the field can contain NULLs; FALSE otherwise.
