What Do You Mean By Not Null With Default? When Will You Use It?

Answer»

This column cannot have nulls and while insertion, if no VALUE is supplied then it will have zeroes, spaces or date/TIME depending on WHETHER it is numeric, character or date/time.
Use it when you do not want to have nulls but at the same time cannot give values all the time you INSERT this row.
