corbeeresearch Posted January 19, 2011 Share Posted January 19, 2011 Hi This part of code `FK_user_project` FOREIGN KEY (`user_id`) REFERENCES `tbl_user` (`id`) ON DELETE CASCADE ON UPDATE RESTRICT; Won't work in the following code. CREATE TABLE IF NOT EXISTS `tbl_issue` ( `id` INTEGER NOT NULL PRIMARY KEY AUTO_INCREMENT, `name` varchar(256) NOT NULL, `description` varchar(2000), `project_id` INTEGER, `type_id` INTEGER, `status_id` INTEGER, `owner_id` INTEGER, `requester_id` INTEGER, `create_time` DATETIME, `create_user_id` INTEGER, `update_time` DATETIME, `update_user_id` INTEGER ) ENGINE = InnoDB ; CREATE TABLE IF NOT EXISTS `tbl_user` ( `id` INTEGER NOT NULL PRIMARY KEY AUTO_INCREMENT, `email` Varchar(256) NOT NULL, `username` Varchar(256), `password` Varchar(256), `last_login_time` Datetime, `create_time` DATETIME, `create_user_id` INTEGER, `update_time` DATETIME, `update_user_id` INTEGER ) ENGINE = InnoDB ; CREATE TABLE IF NOT EXISTS `tbl_project_user_assignment` ( `project_id` Int(11) NOT NULL, `user_id` Int(11) NOT NULL, `create_time` DATETIME, `create_user_id` INTEGER, `update_time` DATETIME, `update_user_id` INTEGER, PRIMARY KEY (`project_id`,`user_id`) ) ENGINE = InnoDB ; -- The Relationships ALTER TABLE `tbl_issue` ADD CONSTRAINT `FK_issue_project` FOREIGN KEY (`project_id`) REFERENCES `tbl_project` (`id`) ON DELETE CASCADE ON UPDATE RESTRICT; ALTER TABLE `tbl_issue` ADD CONSTRAINT `FK_issue_owner` FOREIGN KEY (`owner_id`) REFERENCES `tbl_user` (`id`) ON DELETE CASCADE ON UPDATE RESTRICT; ALTER TABLE `tbl_issue` ADD CONSTRAINT `FK_issue_requester` FOREIGN KEY (`requester_id`) REFERENCES `tbl_user` (`id`) ON DELETE CASCADE ON UPDATE RESTRICT; ALTER TABLE `tbl_project_user_assignment` ADD CONSTRAINT `FK_project_user` FOREIGN KEY (`project_id`) REFERENCES `tbl_project` (`id`) ON DELETE CASCADE ON UPDATE RESTRICT; ALTER TABLE `tbl_project_user_assignment` ADD CONSTRAINT `FK_user_project` FOREIGN KEY (`user_id`) REFERENCES `tbl_user` (`id`) ON DELETE CASCADE ON UPDATE RESTRICT; -- Insert some seed data so we can just begin using the database INSERT INTO `tbl_user` (`email`, `username`, `password`) VALUES ('test1@notanaddress.com','Test_User_One', MD5('test1')), ('test2@notanaddress.com','Test_User_Two', MD5('test2')) ; Where did I go wrong?
