Answer
ENUM restricts a column to a predefined list of values, ensuring consistent data input.
Quick Answer
ENUM defines a column that can only store one value from a predefined list. CREATE TABLE t (status ENUM("active", "inactive", "pending")). Stored as an integer internally (1-2 bytes) but displayed as the string. Compared as strings in queries. Advantage: storage efficient, enforces valid values. Downside: adding new values requires ALTER TABLE (which can lock the table).
