MySQL does not have the built-in BOOLEAN or BOOL data type. To represent boolean values, MySQL uses the smallest integer type which is TINYINT(1) . In other words, BOOLEAN and BOOL are synonyms for TINYINT(1).
A value of zero is considered false. Nonzero values are considered true. MySQL saves boolean data as tinyint (1) that is, 1 or 0, and not True/False values.
