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.

Solution

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.

OTHER TIPS

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`)

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;

`

worked for me
