Answer / shailesh
First of all the way this question is asked is totally wrong. The learner may have to ask which data type does not allow null values.
All data types will allow to insert null values unless the Primary Key or Not Null constraint is defined on a column.

Answer / rajesh
The first answer is wrong, because 'NULL' is string its not null.
If u give null in insert query as second parameter the row will be inserted.

Answer / nanne saheb c
Can't insert NULL value in DATE data type. Please find the below practical as example.
CREATE TABLE Example(
name VARCHAR(30),
regist DATE,
PRIMARY KEY(name)
);
INSERT INTO Example VALUES ('anyname','NULL');
ORA-01841: (full) year must be between -4713 and +9999, and not be 0
