If INSERT INTO can not fulfill the requirement, then the constraint DEFAULT is used for giving a default entry to a specific column. Here is an example for understanding the structure:
(Teacher ID integer Unique,
Score DEFAULT 82);
Then the given statement will run.
The output will be like this;
11 John Henry 82
Here, we have used 82 as a default entry for the column Score. On the other hand, we could not give a value to Score column by using the statement INSERT INTO.
