BIT

BIT is a SQL data type in the Data Types category. Stores bit values. Default length is 1 bit. Can store up to 64 bits in MySQL. The syntax is BIT(length). It returns bit value. A typical example: CREATE TABLE flags (permissions BIT(8)); -- 8-bit bitmask, e.g. b'1101' = 13 INSERT INTO flags VALUES (b'10101010'); A close relative is INT, which standard integer type. Range: -2147483648 to 2147483647 (signed). Use BIGINT for larger values. A close relative is VARCHAR(n), which variable-length string with a maximum length. Most common string type. Efficient for varying-length data. A close relative is TEXT, which for large text content (up to 65535 bytes in MySQL). Variants: TINYTEXT, TEXT, MEDIUMTEXT, LONGTEXT.
