Question :

Suppose that a table has 9 columns. It is known that we only need to provide values for 4 columns explicitly to insert a new row successfully.

Assume that there are n columns with default values and there are m columns with NULL values.

What is the minimum value for n + m? (You can consider the auto-increment case for the primary key.)
