Not Null can not be used along other constraint in a column of a table
Question
Not Null can not be used along other constraint in a column of a table
Solution
That statement is not entirely correct. The NOT NULL constraint can indeed be used with other constraints in a column of a table in SQL. The NOT NULL constraint simply specifies that a column cannot store a NULL value. It can be used with other constraints such as UNIQUE, CHECK, FOREIGN KEY, and PRIMARY KEY constraints.
Here is an example of how you can use NOT NULL with other constraints:
CREATE TABLE Employees (
ID int NOT NULL,
LastName varchar(255) NOT NULL,
FirstName varchar(255),
Age int,
