创建带有 FOREIGN KEY的数据表:

SQL Server / Oracle / MS Access

CREATE TABLE Project
(
    ProjectID int NOT NULL PRIMARY KEY,
    ProjectName varchar(100) NOT NULL,
    ProjectManagerId int FOREIGN KEY REFERENCES Employee(EmployeeId)
)

 My SQL

CREATE TABLE Project
(
    ProjectId int NOT NULL,
    ProjectName varchar(100) NOT NULL,
    ProjectManagerId int,
    PRIMARY KEY (ProjectId ),
    FOREIGN KEY (ProjectManagerId) REFERENCES Employee(EmployeeId)
)

 

若果你想给 foreign key 约束取三个名字:
Oracle,MySQL / SQL Server / Oracle / MS Access:

CREATE TABLE Project
(
    ProjectId int NOT NULL,
    ProjectName varchar(100) NOT NULL,
    ProjectManagerId int,
    PRIMARY KEY (ProjectId ),
    CONSTRAINT fk_EmployeeId FOREIGN KEY (ProjectManagerId )
    REFERENCES Employee(EmployeeId)
)

 

使用ALTER TABLE设置 FOREIGN KEY :

SQL Server / MySQL / Oracle / MS Access:

    ALTER TABLE Project
    ADD FOREIGN KEY (ProjectManagerId )
    REFERENCES Employee(EmployeeId)

 

删除 PRIMARY KEY:

SQL Server / Oracle / MS Access:

   ALTER TABLE Project
    DROP CONSTRAINT fk_EmployeeId

  My SQL:

    ALTER TABLE Orders
    DROP FOREIGN KEY fk_EmployeeId
