Im workin in mySQL workbench 8.0CE, i've created two tables, one for person and another one for persons direction, i'm trying to export data, but it throws and error

This is the sql code

ENGINE = InnoDB;
next i append EER Diagram img
Note: "Personas" id field is at last, beacuse i deleted a foreign key connection.
Somehow i fixed it, unchecked user default global settings in model options, and
INDEX `fk_PersonaDireccion_idx` (`idPersona` ASC) VISIBLE
disapeared, now "direccion" table got like this
CREATE TABLE IF NOT EXISTS `dinSchema`.`direccion` (

I modelled a really simple DB for the first time and trying to insert the queries:
CREATE TABLE `product` (
`pid` varchar(255) NOT NULL,
`mfr` varchar(255) NULL,
`pnum` varchar(255) NOT NULL,
`ssku` varchar(255) NULL,
PRIMARY KEY (`pid`)
);
CREATE TABLE `detail` (
`pid` varchar(255) NOT NULL,
`sdesc` varchar(255) NULL,
`supplier` varchar(255) NULL,
PRIMARY KEY (`pid`)
);
CREATE TABLE `images` (
`pid` varchar(255) NOT NULL,
`url` varchar(255) NULL,
`alt` varchar(255) NULL,
`position` varchar(255) NULL,
PRIMARY KEY (`pid`)
);
ALTER TABLE `detail` ADD CONSTRAINT `fk_detail` FOREIGN KEY (`pid`) REFERENCES `product` ();
ALTER TABLE `images` ADD CONSTRAINT `pid` FOREIGN KEY () REFERENCES `product` ();
... but I get this error:
You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ') REFERENCES `product` ()' at line 1
what am I doing wrong?
You must pass the column name to the REFERENCES clause:
REFERENCES product(pid);
Also, you're creating a blank foreign key on the images constraint:
FOREIGN KEY () REFERENCES `product` ();
I'm trying to create a few tables and one of them has should have foreign keys referencing the other tables, but MySQL Workbench keeps giving me "Error Code: 1215. Cannot add foreign key constraint". This happens if I try to create them during the table creation and if I just create the table and then try to add FK through ALTER. I just can't figure out the problem. I've tried both with and without ENGINE = InnoDB that I saw some people suggest on the web. And yes, tables kommune and person has been created.
CREATE TABLE kommune (
Kommunenr varchar(4) NOT NULL,
Kommunenavn varchar(45) NOT NULL,
PRIMARY KEY (Kommunenr));
CREATE TABLE person (
PersonID varchar(4) NOT NULL,
Fornavn varchar(45) NOT NULL,
Etternavn varchar(45) NOT NULL,
Postnr varchar(4) NOT NULL,
Poststed varchar(45) NOT NULL,
PRIMARY KEY (PersonID));
CREATE TABLE oppdrag (
Oppdragsnr varchar(5) NOT NULL,
Eiendomnr varchar(4) NOT NULL,
Gateadresse varchar(45) NOT NULL,
Postnr varchar(4) NOT NULL,
Poststed varchar(45) NOT NULL,
Kommunenr varchar(4) NOT NULL,
Prisantydning varchar(10) NOT NULL,
Solgt boolean NOT NULL,
PRIMARY KEY (Oppdragsnr),
FOREIGN KEY (Postnr) REFERENCES person(Postnr),
FOREIGN KEY (Poststed) REFERENCES person(Poststed),
FOREIGN KEY (Kommunenr) REFERENCES kommune(Kommunenr));
Check the following lines:
FOREIGN KEY (Postnr) REFERENCES person(Postnr),
FOREIGN KEY (Poststed) REFERENCES person(Poststed),
but in your table structure:
CREATE TABLE person (
PersonID varchar(4) NOT NULL,
Fornavn varchar(45) NOT NULL,
Etternavn varchar(45) NOT NULL,
Postnr varchar(4) NOT NULL,
Poststed varchar(45) NOT NULL,
PRIMARY KEY (PersonID));
Postnr, Poststed are neither unique or not primary key. To make foreign key, the referring column in the base table must be an indexed column
I'm Confused as to why my code isnt working.

Im trying to create a table but it says i have an error when i dont think i do. I'll be very greatful if you can see what i've done wrong. Thanks everyone that helps!
You forgot a comma.
...
PRIMARY KEY (VEHICLE_VEH_ID , DRIVER_DR_ID), -- Need a comma here
INDEX (DRIVER_DR_ID),
...
You first need to create these two tables:
CREATE TABLE DRIVER (
DR_ID INT NOT NULL PRIMARY KEY,
DR_TITLE VARCHAR(15) NOT NULL,
DR_FNAME VARCHAR(45) NOT NULL,
DR_LNAME VARCHAR(45) NOT NULL,
DR_DOB DATETIME NOT NULL,
DR_LICENCENO VARCHAR(45) NOT NULL,
DR_PHONE VARCHAR(15) NOT NULL,
DR_EMAIL VARCHAR(45) NOT NULL);
CREATE TABLE VEHICLE (
VEH_ID INT NOT NULL PRIMARY KEY,
VEH_REG VARCHAR(15) NOT NULL,
VEH_MAKE VARCHAR(45) NOT NULL,
VEH_MODEL VARCHAR(45) NOT NULL,
VEH_MILEAGE INT NOT NULL,
VEH_MOTDATE DATETIME NOT NULL,
VEH_SERVICEDATE DATETIME NOT NULL);
Then use this sql code to create the last one, that references the two tables above:
CREATE TABLE DELIVERY (
VEHICLE_VEH_ID INT NOT NULL,
DRIVER_DR_ID INT NOT NULL,
DEL_DATE DATETIME NOT NULL,
DEL_TIME DATETIME NOT NULL,
PRIMARY KEY (VEHICLE_VEH_ID , DRIVER_DR_ID),
INDEX (DRIVER_DR_ID),
INDEX (VEHICLE_VEH_ID),
CONSTRAINT FK_VEHICLE_HAS_DRIVER_VEHICLE FOREIGN KEY (VEHICLE_VEH_ID) REFERENCES VEHICLE (VEH_ID) ,
CONSTRAINT FK_VEHICLE_HAS_DRIVER_DRIVER FOREIGN KEY (DRIVER_DR_ID) REFERENCES DRIVER (DR_ID));
Your code is also missing two commas plus the REFERENCES keyword in the FK_VEHICLE_HAS_DRIVER_DRIVER foreign key constraint.
