如何建立forign键作为主键，并与工会重点

Question

我有一个用户表相关联的，它有一个工会重点open_id，现在我想建立一个表 ，它需要与工会相关的主键键。顺便说一句，我使用mysql5.6和open_id是varchar。 对不起，我不是英语很好的......

CREATE TABLE click ( 
open_id varchar(11) NOT NULL, 
click_count int(11) NOT NULL DEFAULT '0', 
PRIMARY KEY (open_id), 
CONSTRAINT click_ibfk_1 FOREIGN KEY (open_id) REFERENCES user_info (u_openid) 
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
