Example:
CREATE TABLE IF NOT EXISTS `table`(
`id` int(11) unsigned NOT NULL,
`active` BOOLEAN DEFAULT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
Boolean datatype in mysql: Use "TinyInt(1)"" or "Boolean" (this is the same thing)
"bit(1)" can also work, but it may require a syntax like b'(0) and b'(1) when inserting (not sure).
If there are multiple booleans in the same table, bit(1) is better, otherwise it's the same result.
