I'm trying to create this table :
CREATE TABLE INFORMEPERICIAL (
INFORME_NO INT(3),
PRIMARY KEY (INFORME_NO),
DATEEMISIO DATE NOT NULL,
IMPORTCOBERT DECIMAL(8,2),
PERIT_NO INT(3) NOT NULL,
INFORME VARCHAR(200),
RESULTATPERITATGE VARCHAR(20),
CONSTRAINT RESULTATPERITATGE_CK CHECK (RESULTATPERITATGE IN ('COBERT_TOTAL','COBERT_PARCIAL','SENSE_COBERTURA','REPARAT')),
ESTATINFORME VARCHAR(20),
CONSTRAINT ESTATINFORME_CK CHECK ESTATINFORME IN ('PENDENT','TANCAT'),
CONSTRAINT INFORMEPERICIAL_FK_PERIT FOREIGN KEY (PERIT_NO) REFERENCES PERIT (NUMERO),
CONSTRAINT INFORMEPERICIAL_CK_INFORME_NO_NUM_POSITIU CHECK (INFORME_NO > 0)
);
But, i'm having troubles with the foreign key.
This is my ok-formed "Perit" table" :
CREATE TABLE PERIT (
COGNOM1 VARCHAR(30) NOT NULL,
COGNOM2 VARCHAR(30) NOT NULL,
DATANAIX DATE NOT NULL,
NOM VARCHAR(30) NOT NULL,
NIF VARCHAR(10) NOT NULL,
LOGIN VARCHAR(50) NOT NULL,
PASSWORDMD5 VARCHAR(50) NOT NULL,
NUMERO INT(3) NOT NULL AUTO_INCREMENT,
PRIMARY KEY (NUMERO)
);
I can't undesrtand why I'm getting the error 1005, the field-types are equals!
Issue is here:
CONSTRAINT ESTATINFORME_CK CHECK ESTATINFORME IN ('PENDENT','TANCAT'),
Wrap the condition in parentheses:
CONSTRAINT ESTATINFORME_CK CHECK (ESTATINFORME IN ('PENDENT','TANCAT')),

I'm creating some mysql code with phpmyadmin for a school project and am getting the error "#1005 - Can't create table world_cup.goal (errno: 150 "Foreign key constraint is incorrectly formed") (Details…)".
I can't figure out why I'm getting the error. If I delete the GOAL entity, it still gives the error, but with the CARD entity. In fact, it doesn't like the last 4 entities I created. It has to do with the the foreign key I think.
WHAT I'VE TRIED:
making sure that all the FK and the referenced PK are the same datatype. They match perfectly.
I can't think of anything else to try.
This is due tomorrow so any help would be greatly appreciated! Thanks!
Here is the code:
DROP DATABASE IF EXISTS WORLD_CUP;
CREATE DATABASE WORLD_CUP;

CREATE TABLE TEAM(

CREATE TABLE CARD(

PRIMARY KEY(SPno, PCid, PGid),
FOREIGN KEY (SPno) REFERENCES PLAYER(Pno),
FOREIGN KEY(PCid) REFERENCES TEAM(Cid),
FOREIGN KEY (PGid) REFERENCES GAME(Gid)
);
It's because the primary key on PLAYER is composite, so the foreign key that points to it has to be composite too.
My version of GOAL - note addition of GPCid and its inclusion in the foreign key:
CREATE TABLE GOAL(
GPCid varchar(2) not null,
GPno int NOT NULL,
GMinute varchar(6) NOT NULL,
GoalType char NOT NULL,
GGid varchar(2) NOT NULL,
PRIMARY KEY(GPno, GGid, GMinute) ,
FOREIGN KEY (GPCid,GPno) REFERENCES PLAYER(PCid,Pno),
FOREIGN KEY (GGid) REFERENCES GAME(Gid)
);
And similarly for CARD etc.
I am receiving an error when attempting to create some tables in mysql with the foreign key
CREATE TABLE session (
code CHAR(2) NOT NULL,
date DATE,
room VARCHAR(30) NULL,
CONSTRAINT session_pk PRIMARY KEY (date),
CONSTRAINT session_fk FOREIGN KEY (code)
REFERENCES module(code));
CREATE TABLE module (
code CHAR(2) NOT NULL,
name VARCHAR(30) NOT NULL,
cost DECIMAL(8,2) NOT NULL,
credits TINYINT NOT NULL,
course_code CHAR(3) NOT NULL,
CONSTRAINT module_pk PRIMARY KEY (code));
Here are the two tables I am trying to create, the syntax I've used matches w3 schools and both data types are the same so I cannot see how this is incorrect, any help would be appreciated thanks :)
You're trying to create a foreign key on table before creating the referencing table.
Interchanging the order of query will work :
CREATE TABLE module (
`code` CHAR(2) NOT NULL,
name VARCHAR(30) NOT NULL,
cost DECIMAL(8,2) NOT NULL,
credits TINYINT NOT NULL,
course_code CHAR(3) NOT NULL,
CONSTRAINT module_pk PRIMARY KEY (`code`));
CREATE TABLE `session` (
`code` CHAR(2) NOT NULL,
`date` DATE,
room VARCHAR(30) NULL,
CONSTRAINT session_pk PRIMARY KEY (`date`),
CONSTRAINT session_fk FOREIGN KEY (`code`)
REFERENCES module(`code`));
Try this
CREATE TABLE module (
code CHAR(2) NOT NULL,
name VARCHAR(30) NOT NULL,
cost DECIMAL(8,2) NOT NULL,
credits TINYINT NOT NULL,
course_code CHAR(3) NOT NULL,
CONSTRAINT module_pk PRIMARY KEY (code));
CREATE TABLE session (
code CHAR(2) NOT NULL,
date DATE,
room VARCHAR(30) NULL,
CONSTRAINT session_pk PRIMARY KEY (date),
CONSTRAINT session_fk FOREIGN KEY (code)
REFERENCES module(code));
I get this following error for some reason, and I know it has to do with the foreignkey I just added "UsesTruck" However I don't know WHAT it is I did wrong.. I have included only the tables I think are important for this issue.

FOREIGN KEY (Location_Address_Drop) REFERENCES Location (Address));
Try to run create Truck table firstly.
Here is the code below, I'm not sure what this error means...
All I know is that it has something to do with the employeeshifts table.
Does it have something to do with foreign keys?

You need to reference UNIQUE or PRIMARY KEY column:
CREATE TABLE EmployeeShifts (
DesiredShift DATETIME NOT NULL,
EmployeeWorking VARCHAR(90) NOT NULL,
DateOfShift DATE,
PRIMARY KEY(DesiredShift, EmployeeWorking, DateOfShift),
FOREIGN KEY (EmployeeWorking) REFERENCES Employee(Name), -- name is not UNIQUE/PK
FOREIGN KEY (DesiredShift) REFERENCES Shifts(ShiftTime)
);
to:
CREATE TABLE EmployeeShifts (
DesiredShift DATETIME NOT NULL,
EmployeeID INT NOT NULL, -- here
DateOfShift DATE,
PRIMARY KEY(DesiredShift, EmployeeID, DateOfShift),
FOREIGN KEY (EmployeeID) REFERENCES Employee(EmployeeID),
FOREIGN KEY (DesiredShift) REFERENCES Shifts(ShiftTime)
);

When I try to source these tables into MySQL, and it created all the tables. Then I start to populate the tables, and it will not let me populate the last table Rental_Invoice. Any suggestions?
The error is

);
Initial problem
Just a random guess since I don't have MySQL installed anywhere at the moment. But Client_ID in the dependent table is a VARCHAR and it refers to an INTEGER column in the parent table.
After Edit
The foreign key constraint is caused by inserting a row into Rental_Invoice that does not have a corresponding row in Client_Contact. In other words, your data violates the Rental_Invoice_fk_Client_Contact foreign key constraint that requires that Rental_Invoice.Client_ID refers to an existing row in Client_Contact with a matching Client_ID.
