How to set default values in a MySQL database

In MySQL database, you can use the DEFAULT keyword to set a default value.

When creating a table, you can use the DEFAULT keyword to set a default value for a column, as shown below:

CREATE TABLE table_name (
    column_name data_type DEFAULT default_value
);

You can also modify the default value of an existing table using the ALTER TABLE statement, as shown below:

ALTER TABLE table_name 
ALTER COLUMN column_name SET DEFAULT default_value;

It is important to note that if a default value is not specified when creating a table and no value is provided for a column when inserting data, the column will be set to NULL.
