Mysql创建具有自动递增ID的表给出错误

Question

我只是找不到这段代码有什么问题......

connection.query('CREATE TABLE posts (postid int NOT NULL AUTO_INCREMENT, posttitle varchar(255) NOT NULL, postdate datetime NOT NULL, deleted boolean, ownerid int PRIMARY KEY (postid) )');

我得到了错误

Error: ER_PARSE_ERROR: 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 '(postid) )' at line 1

我使用 node 和 mysql npm 模块。请帮忙。

您忘记了ownerid int 和PRIMARY KEY (postid) 之间的,，如下所示

ownerid int PRIMARY KEY (postid)
           ^...Here  

你的CREATE TABLE 声明应该是

CREATE TABLE posts (postid int NOT NULL AUTO_INCREMENT, 
posttitle varchar(255) NOT NULL, 
postdate datetime NOT NULL, 
deleted boolean, 
ownerid int, //Add comma here
 PRIMARY KEY (postid));
