Can You insert a row containing a null attribute value using SQL?

Answer 1

You cannot do it, if the column is not null in the table.

Assuming you have a table TBL with columns a, b, c

insert into TBL (a, b, c) values ('AAA', null, 'BBB')

Now, the value null would be stored in the database for the column 'b'

Answer 2

Yes, you can insert a row with a null attribute value using SQL by simply not specifying a value for that attribute in the INSERT statement or explicitly using the keyword NULL. For example, if you have a column called "email" and want to insert a row without specifying an email value, you can do so by executing:

INSERT INTO table_name (email) VALUES (NULL);
