Answer
A default value is used when no explicit value is provided during insertion, ensuring consistent data entry.
Quick Answer
DEFAULT sets a value used when no value is provided for a column during INSERT. Examples: created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP, status VARCHAR(20) DEFAULT "active", score INT DEFAULT 0. If you INSERT without specifying the column, the default is used. Defaults can be constant values or a limited set of MySQL functions (CURRENT_TIMESTAMP, NOW(), etc.).
