Hi
This part of code
PHP 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.
PHP 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?
Thanks
