[Quoted] Dear experts,
Our student team is currently developping a project for a course and we are wondering about the NULL symbol.
What exactly is the NULL?
Can a VARCHAR2 and DATE information be NULL?
This information would be helpful to determine our default values and constraints.
Any information would be helpful.
