INSERT INTO `users` (`id`, `string`, `email`, `integer`, `float`, `boolean`, `null`, `date`, `time`, `binary_or_blob`, `nullable_string`, `nullable_integer`) VALUES (1,'example@exa','[email protected]',1245,2.1,1,-321,NULL,NULL,'\\x92\0\0\0\0\0\0\0','abcde',NULL),
(2,'あいうえお','invalid@email',0,-23.4422,0,321,NULL,NULL,'\\x92\\x92\0\0\0',NULL,12),
(3,'+-l;a*&^%$','[email protected]',-1,21.2321,NULL,-231321,'2019-10-31','2019-10-31 16:27:21',NULL,'abc123',-123);
