How to Set Not Null in Column for Database Table in PhpMyAdmin | Add Not Null Constraint

In this phpmyadmin tutorial for beginners you will learn how to add not null in column in existing or new tables in databases in phpmyadmin.

** In a database, the NOT NULL constraint is used to ensure that a column cannot have a NULL value. This means that every row in the table must have a value for that column; it cannot be left empty. This is useful for ensuring data integrity, as it guarantees that certain fields will always contain valid data.
