sql 创建表出现问题

解决

将表名字段名的单引号改为键盘左上角的英文反引号

• 正确的

create table `mood` (
  `id` varchar(32) not null,
  `content` varchar(256) Default Null,
  `user_id` varchar(32) Default Null,
  `praise_num` int(11) Default NULL,
  `publish_time` datetime Default NULL,
  primary key (`id`),
  Key `mood_user_id_index` (`user_id`) Using Btree
)engine=InnoDb Default Charset=utf8;

• 错误的

drop table If exists 'mood';
create table 'mood' (
  'id' varchar(32) not null,
  'content' varchar(256) Default Null,
  'user_id' varchar(32) Default Null,
  'praise_num' int(11) Default NULL,
  'publish_time' datetime Default NULL,
  primary key ('id'),
  Key 'mood_user_id_index' ('user_id') Using Btree
)engine=InnoDb Default Charset=utf-8;
