SQL-query error date - mysql

why does MySQL give me #1063 - Wrong column specification for column 'Date' error if I want to import this query? What I need to have in that row is Date with format: YYYY/MM/DD. Can someone help me and explain whats wrong and why this is wrong so I can learn :) Thank you!

Failed to add the foreign key constraint, MySQL

I have this error on PopSQL :
Error: Failed to add the foreign key constraint. Missing index for constraint 'etape__ibfk_1' in the referenced table 'etapexprojet_'
Error Code: ER_FK_NO_INDEX_PARENT
This is my code, i'm only creating tables and it has a problem in the "Etape_" part, i really, don't know why
I'm really, really new to SQL. Like... this is my first time doing this
--Client
CREATE TABLE IF NOT EXISTS jegere.client_ (
idClient INT PRIMARY KEY,
nomClient VARCHAR(45) NOT NULL,
adresse VARCHAR(45) NOT NULL UNIQUE,
telephone VARCHAR(45) NOT NULL UNIQUE,
adresseCourriel VARCHAR(45) NOT NULL UNIQUE
);
--Employés
CREATE TABLE IF NOT EXISTS jegere.Employe_ (
idEmploye INT PRIMARY KEY,
nomEmploye VARCHAR(45) NOT NULL,
adresse VARCHAR(45) NOT NULL UNIQUE,
telephone VARCHAR(45) NOT NULL UNIQUE,
adresseCourriel VARCHAR(45) NOT NULL UNIQUE
);
--Projet
CREATE TABLE IF NOT EXISTS jegere.Projet_ (
idProjet INT PRIMARY KEY,
idClient INT ,
nomProjet VARCHAR(45) NOT NULL ,
dateDebut DATE NOT NULL ,
dateFin DATE,
idResponsable INT NOT NULL ,
FOREIGN KEY (idClient ) REFERENCES jegere.Client_ (idClient ),
FOREIGN KEY (idResponsable ) REFERENCES jegere.Employe_ (idEmploye )
);
--RessourcesProjet
CREATE TABLE IF NOT EXISTS jegere.RessourcesProjet_ (
idProjet INT NOT NULL,
idEmploye INT NOT NULL,
nbrHeure INT NOT NULL,
PrixHeure FLOAT NOT NULL,
PRIMARY KEY(idProjet, idEmploye),
FOREIGN KEY(idProjet) REFERENCES projet_(idProjet),
FOREIGN KEY(idEmploye) REFERENCES employe_(idEmploye)
);
--Etape X Projet
CREATE TABLE IF NOT EXISTS jegere.EtapexProjet_ (
idEtape INT NOT NULL,
idProjet INT NOT NULL,
dateDebut DATE NOT NULL ,
dateFin DATE,
PRIMARY KEY(idProjet, idEtape),
FOREIGN KEY(idProjet) REFERENCES projet_(idProjet)
);
--Etapes
CREATE TABLE IF NOT EXISTS jegere.Etape_ (
idEtape INT,
nomEtape VARCHAR(45) NOT NULL,
Livrable VARCHAR(100) NOT NULL,
PRIMARY KEY(idEtape),
FOREIGN KEY(idEtape) REFERENCES etapexprojet_(idEtape)
);

The referenced column in a foreign key needs to be indexed, so you need to add an index on the idEtape column in etapexprojet:
--Etape X Projet
CREATE TABLE IF NOT EXISTS jegere.EtapexProjet_ (
idEtape INT NOT NULL,
idProjet INT NOT NULL,
dateDebut DATE NOT NULL ,
dateFin DATE,
PRIMARY KEY(idProjet, idEtape),
INDEX (idEtape),
FOREIGN KEY(idProjet) REFERENCES projet_(idProjet)
);
Having it as part of the primary key isn't sufficient. A prefix of an index is also an index, but idEtape is a later part of the primary key index, so it's not indexed by itself.
Another solution is to change the order of the primary key:
PRIMARY KEY(idEtape, idProject),

Your last table etape references only the column idetape, but all referenced columns need an index , primary key or UNIQUE constraint.
so add a KEY to your EtapexProjet_ for the column idetape, and you can run the code
CREATE TABLE IF NOT EXISTS EtapexProjet_ (
idEtape INT NOT NULL,
idProjet INT NOT NULL,
dateDebut DATE NOT NULL ,
dateFin DATE,
PRIMARY KEY(idProjet, idEtape),
KEY(idEtape),
FOREIGN KEY(idProjet) REFERENCES Projet_(idProjet)
);

MySQL - Nonsense Syntax Errors

I'm new to programming, and cannot understand the syntax errors that I'm getting.
CREATE SCHEMA IF NOT EXISTS donutsrus;
CREATE TABLE IF NOT EXISTS DONUT (
Donut_ID INT NOT NULL, UNIQUE
Donut_Name VARCHAR (20) NOT NULL, UNIQUE
Description VARCHAR (20) NOT NULL, UNIQUE
Unit_Price NUMERIC (4,2) NOT NULL
PRIMARY KEY (Donut_ID));
CREATE TABLE IF NOT EXISTS SALES_ORDER (
Sales_Order_ID INT NOT NULL, UNIQUE
Sales_Order_Date DATE NOT NULL
Sales_Order_Notes VARCHAR (100)
Customer_ID INT NOT NULL, UNIQUE
PRIMARY KEY (Sales_Order_ID)
FOREIGN KEY (Customer_ID));
CREATE TABLE IF NOT EXISTS CUSTOMER (
Customer_ID INT NOT NULL, UNIQUE
Last_Name VARCHAR (20) NOT NULL
First_Name VARCHAR (20) NOT NULL
Address VARCHAR (50) NOT NULL
Apt VARCHAR (5)
City VARCHAR (20) NOT NULL
State CHAR (2) NOT NULL
Zip NUMBER (5) NOT NULL
Home_Phone NUMBER (10)
Mobile_Phone NUMBER (10)
Other_Phone NUMBER (10)
PRIMARY KEY (Customer_ID));
CREATE TABLE IF NOT EXISTS ORDER_LINE_ITEM (
Donut_ID INT NOT NULL, UNIQUE
Sales_Order_ID INT NOT NULL, UNIQUE
Quantity INT NOT NULL
PRIMARY KEY (Donut_ID, Sales_Order_ID)
FOREIGN KEY (Donut_ID, Sales_Order_ID));
On the Donut table, I get Syntax error: extraneous input found - expected 'opening parenthesis', at the VARCHAR after Donut_Name. At the closing paren after the succeeding 20, I get Syntax error: extraneous input found - expected 'closing parenthesis'.
On the Order Line Item table I get, Syntax Error: 'INT' (int) is not valid input at this position, after the Sales_Order_ID. I also don't understand why it's okay on other lines of code, but not this one.

All the commas before UNIQUE are wrong. Commas are used to separate the columns, not to separate options for a specific column.
CREATE TABLE IF NOT EXISTS DONUT (
Donut_ID INT NOT NULL UNIQUE,
Donut_Name VARCHAR (20) NOT NULL UNIQUE,
Description VARCHAR (20) NOT NULL UNIQUE,
Unit_Price NUMERIC (4,2) NOT NULL,
PRIMARY KEY (Donut_ID));
CREATE TABLE IF NOT EXISTS CUSTOMER (
Customer_ID INT NOT NULL UNIQUE,
Last_Name VARCHAR (20) NOT NULL,
First_Name VARCHAR (20) NOT NULL,
Address VARCHAR (50) NOT NULL,
Apt VARCHAR (5),
City VARCHAR (20) NOT NULL,
State CHAR (2) NOT NULL,
Zip NUMBER (5) NOT NULL,
Home_Phone NUMBER (10),
Mobile_Phone NUMBER (10),
Other_Phone NUMBER (10),
PRIMARY KEY (Customer_ID));
CREATE TABLE IF NOT EXISTS SALES_ORDER (
Sales_Order_ID INT NOT NULL UNIQUE,
Sales_Order_Date DATE NOT NULL,
Sales_Order_Notes VARCHAR (100),
Customer_ID INT NOT NULL,
PRIMARY KEY (Sales_Order_ID),
FOREIGN KEY (Customer_ID) REFERENCES CUSTOMER (Customer_ID));
CREATE TABLE IF NOT EXISTS ORDER_LINE_ITEM (
Donut_ID INT NOT NULL,
Sales_Order_ID INT NOT NULL,
Quantity INT NOT NULL,
PRIMARY KEY (Donut_ID, Sales_Order_ID),
FOREIGN KEY (Donut_ID) REFERENCES DONUT (Donut_ID),
FOREIGN KEY (Sales_Order_ID) REFERENCES SALES_ORDER (Sales_Order_ID));
BTW, the UNIQUE option is not necessary for primary keys, they're automatically made unique. And in ORDER_LINE_ITEM, if the primary key is (Donut_ID, Sales_Order_ID) you probably don't want to make each of those columns unique by themselves. This prevents the same donut from being in multiple orders, or an order having more than one donut type. Similarly, Customer_ID should not be unique in SALES_ORDER; a customer can obviously have more than one order.
Your FOREIGN KEY lines were missing the references of the foreign keys. And the tables with the foreign keys need to be created after the tables they reference, so I moved SALES_ORDER down to after CUSTOMER.

You need to make SSN in employee table a unique key, which is one in real life any way, so that it can be referenced as a foreign key:
CREATE TABLE Employee(
EmployeeID int PRIMARY KEY,
FirstName varchar (50) NOT NULL ,
LastName varchar (50) NOT NULL ,
Address varchar (60) NULL ,
City varchar (25) NULL ,
State varchar (15) NULL ,
Phone varchar (16) NULL,
SSN varchar (16) NOT NULL,
unique(SSN)
);

At a minimum, there is no password data type in SQL Server. Since you have provided no details about how you're storing data, I converted it to varchar(50).

Could probably be more compacted with normalization but it should work based on the code you have provided.

foreign key reference syntax error

I am having trouble creating members table with the following code. check the manual that corresponds to your MySQL server version for the right syntax to use near 'schoolID int NOT NULL FOREIGN KEY REFERENCES schools(schoolID),' at line 1
What is wrong with the syntax?
