MySql表，错误＃1064＆amp;错误＃1068定义了多个主键

Question

我尝试安装MySql表时遇到错误，错误：

  

“＃1064 - 您的SQL语法出错”

和错误：

  

“＃1068 - 定义了多个主键”

这是数据库：

CREATE TABLE messages (
msg_id INT PRIMARY KEY AUTO_INCREMENT,
message VARCHAR(200),
uid_fk INT(10),
ip VARCHAR(45),
created INT(10),
uploads VARCHAR(50),
profile_uid INT(10)

PRIMARY KEY (`msg_id`),
KEY `uid_fk` (`uid_fk`)

);


CREATE TABLE comments (
com_id INT PRIMARY KEY AUTO_INCREMENT,
comment VARCHAR(200),
msg_id_fk INT(10),
uid_fk INT(10),
ip VARCHAR(45),
created INT(10),

PRIMARY KEY (`com_id`),
KEY `msg_id_fk` (`msg_id_fk`),
KEY `uid_fk` (`uid_fk`)

);


CREATE TABLE likes (
like_id INT PRIMARY KEY AUTO_INCREMENT,
msg_id_fk INT(10),
uid_fk INT(10),

PRIMARY KEY (`like_id`),
KEY `msg_id_fk` (`msg_id_fk`),
KEY `uid_fk` (`uid_fk`)

);


CREATE TABLE user_uploads (
id INT PRIMARY KEY AUTO_INCREMENT,
image_path VARCHAR(500),
uid_fk INT(10),

PRIMARY KEY (`id`),
KEY `uid_fk` (`uid_fk`)

);


CREATE TABLE follow_user (
fid INT PRIMARY KEY AUTO_INCREMENT,
uid_fk INT(10),
following_uid INT(10),

PRIMARY KEY (`fid`),
KEY `uid_fk` (`uid_fk`)

);

这些是错误图片：

如何解决？

Answer 1

使用内联语法（msg_id INT PRIMARY KEY AUTO_INCREMENT）或之后声明（PRIMARY KEY ( com_id )），而不是两者：它们发生冲突。

Answer 2

消息表中的语法错误只是profile_uid INT(10)行末尾缺少逗号。
