You have several problems. Both tables have duplicate keys.
You don't have a (c_id) key in table2 to add a constraint to.

I can't seem to be able to create foreign keys. Here are my create procedures and the error I am receiving.
CREATE TABLE `test1` ( `a_id` smallint(6) NOT NULL default '0', PRIMARY KEY (`a_id`), KEY `a_id` (`a_id`) ) TYPE=InnoDB;
CREATE TABLE `test2` ( `b_id` smallint(6) NOT NULL default '0', `c_id` smallint(6) NOT NULL default '0', PRIMARY KEY (`b_id`), KEY `b_id` (`b_id`) ) TYPE=InnoDB;
mysql> alter table test2 add constraint -> FOREIGN KEY (c_id) REFERENCES test1 (a_id);
ERROR 1005: Can't create table './inventory/#sql-267_4.frm' (errno: 150)
This seems very simple. Is there a problem in my alter statement?
