Musíte mít sloupec v keywords
tabulky pro uložení cizího klíče.
Takhle
CREATE TABLE `jobs` (
`title` text NOT NULL,
`type` text NOT NULL,
`location` text NOT NULL,
`salary` int(11) NOT NULL,
`description` text NOT NULL,
`date` date NOT NULL,
`job_id` int(11) NOT NULL AUTO_INCREMENT,
PRIMARY KEY (`job_id`)
) ENGINE=InnoDB AUTO_INCREMENT=28 DEFAULT CHARSET=latin1;
CREATE TABLE `keywords` (
`keyword_id` int(11) NOT NULL AUTO_INCREMENT,
`keyword` text NOT NULL,
`job_id` int(11) NOT NULL, #<- new column
PRIMARY KEY(`keyword_id`),
FOREIGN KEY (job_id) REFERENCES jobs(job_id)
) ENGINE=InnoDB AUTO_INCREMENT=28 DEFAULT CHARSET=latin1;
