解決Mysql ：datetime(0) NULL DEFAULT NULL報錯

1、錯誤信息

CREATE TABLE `file`  (
  `id` varchar(32) CHARACTER SET utf8mb4 COLLATE utf8mb4_general_ci NOT NULL COMMENT '文件md5',
  `name` varchar(128) CHARACTER SET utf8mb4 COLLATE utf8mb4_general_ci NOT NULL,
  `create_time` datetime(0) NULL DEFAULT NULL,
  `update_time` datetime(0) NULL DEFAULT NULL,,
  PRIMARY KEY (`id`)
)

You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '(0) NULL  DEFAULT NULL,
  `update_time` datetime(0) NULL DEFAULT NULL,
  `tena' at line 3

2、問題解決
1)問題發現是第三行，那就是datetime字段，在網上查詢是mysql版本時間字段不能設置爲0。給一個默認值

CREATE TABLE `file`  (
  `id` varchar(32) CHARACTER SET utf8mb4 COLLATE utf8mb4_general_ci NOT NULL COMMENT '文件md5',
  `name` varchar(128) CHARACTER SET utf8mb4 COLLATE utf8mb4_general_ci NOT NULL,
  ##默認是1970-01-01 00:00:00，中國時間要加8
  `create_time` datetime DEFAULT '1970-01-01 08:00:00',
  `update_time` datetime DEFAULT '1970-01-01 08:00:00',
  PRIMARY KEY (`id`)
)

2)直接刪除 (0) NULL
