INSERT INTO activiti-demo.user(id, password, rank, username, leader_id, in_time`)
VALUES
(1, '123123', '管理员', 'admin', NULL, '2019-04-22 14:19:23'),
(3, '123123', '总经理', 'user1', NULL, '2019-04-22 14:19:23'),
(2, '123123', '部门经理', 'user2', 3, '2019-04-22 14:19:23'),
(5, '123123', '员工', 'user3', 2, '2019-04-22 14:21:38'),
(6, '123123', '员工', 'user4', 2, '2019-04-22 14:22:56');
