Create table failed in MySQL - mysql

Question

I have designed the schema and generated the create SQL below using the MySQLWorkbench.
This query through this error: Can't create table 'museum.statue_details'. Could someone please tell me what seems to be the problem and how to solve it? Thanks.

Answer 1

You have many constraints with the same name,change them or let mysql name them.
CONSTRAINT `artefact_id`
this repeats everywhere.There are others.
Also in museum.creator you have missing columns:
CONSTRAINT `epoch_id`
FOREIGN KEY ()
REFERENCES `museum`.`epoch` ()
You probably want epoch_id in between.All those fixed, it runs on my machine.

Answer 2

you should give other name of your foreign keys like that:
insetead of
CONSTRAINT `artefact_id`
FOREIGN KEY (`artefact_id`)
REFERENCES `museum`.`artefact` (`artefact_id`)
do:
CONSTRAINT FK_mykey --> give name as you like here to distinguich between others
FOREIGN KEY (`artefact_id`)
REFERENCES `artefact` (`artefact_id`)

Answer 3

create table syntax:
http://dev.mysql.com/doc/refman/5.7/en/create-table.html
I believe the issue lies with you declaring the table name with {name1}.{name2}.
CREATE TABLE IF NOT EXISTS `collection` (
`collection_id` INT NOT NULL,
`name` VARCHAR(45) NULL,
`type` VARCHAR(45) NULL,
`description` VARCHAR(45) NULL,
`address` VARCHAR(45) NULL,
`phone` VARCHAR(45) NULL,
`current_contact_person` VARCHAR(45) NULL,
PRIMARY KEY (`collection_id`),
UNIQUE INDEX `name_UNIQUE` (`name` ASC))
ENGINE = InnoDB;
