更改表错误 MS SQL

Question

CREATE TABLE EMPLOYEES(
EmployeeNumber INT NOT NULL IDENTITY(1,1)
LastName Char(35)  NOT NULL,
FirstName CHAR(35)  NOT NULL,
Department CHAR(35) NOT NULL,
CONSTRAINT  EMPLOYEE_PK PRIMARY KEY(EmployeeNumber));

CREATE TABLE DEPARTMENT(
DepartmentName CHAR(35) NOT NULL,
Phone CHAR(35)  NOT NULL,
BudgetCode  CHAR(35) NOT NULL,
CONSTRAINT  DEP_PK  PRIMARY KEY(DepartmentName));

I forgot make a department as foreign key in employees, so i did

ALTER TABLE EMPLOYEES ADD CONSTRAINT EMP_DEP_FK
  FOREIGN KEY(Department) REFERENCES DEPARTMENT(DepartmentName)

and this showed me:

The ALTER TABLE statement conflicted with the FOREIGN KEY constraint "EMP_DEP_FK". The conflict occurred in database "WPC", table "dbo.DEPARTMENT", column 'DepartmentName'.

Answer 1

You have a typo in your DEPARTMENT table ==> DepartmetnName .

Should have been DepartmentName instead.
