表作成

• モデルの各エンティティです。
• SQL内では、CREATE TABLEコマンドを使用して新しいテーブルが作成されます。
• テーブルが作成されるときにその名前とその属性が定義されます。
• この値はモデルで指定された値から派生しています。
• プライマリキーの識別など、特定の制約も指定されることがあります。

    -- Alter Tables to add fk constraints -- 

    -- Now all the tables have been created the ALTER TABLE command is used to define some additional 
    -- constraints. These typically constrain values of foreign keys to be associated in some way 
    -- with the primary keys of related tables. Foreign key constraints can actually be specified

    -- i.e. tables may be referenced before they have been created. This method is therefore safer.

Answer 1

ON DELETE CASCADEが

次のようにこれらの条項を削除存在する可能性がある間は句ON UPDATE CASCADEはありません。

CREATE TABLE first_aider(
    staffId INTEGER NOT NULL, 
    name VARCHAR(25), 
    CONSTRAINT pk_first_aider 
    PRIMARY KEY (staffId), 
    FOREIGN KEY(staffId) REFERENCES staff(staffId) ON DELETE CASCADE 
); 

と

を

CREATE TABLE security(
    staffId INTEGER NOT NULL, 
    name VARCHAR(55), 
    CONSTRAINT pk_security 
    PRIMARY KEY (staffId), 
    FOREIGN KEY(staffId) REFERENCES staff(staffId) ON DELETE CASCADE 
); 

と

CREATE TABLE supervisor(
    staffId INTEGER NOT NULL, 
    name VARCHAR(8), 
    CONSTRAINT pk_supervisor 
    PRIMARY KEY (staffId),  
    FOREIGN KEY(staffId) REFERENCES staff(staffId) ON DELETE CASCADE 
); 

Answer 2

外部キー定義は、ここで間違っている：

CREATE TABLE first_aider(
    ...... 
    ...... 
    FOREIGN KEY(staffId) REFERENCES staff(staffId) ON DELETE CASCADE ON UPDATE CASCADE 
); 

Oracleが許可されているthe documentationだけON DELETE CASCADEまたはON DELETE SET NULLによると、ON UPDATE CASCADE句を知りません。 ON UPDATE CASCADEを削除する必要があります。

は、同じエラーがここにある：こちらも

CREATE TABLE security(
    ...... 
    ...... 
    FOREIGN KEY(staffId) REFERENCES staff(staffId) ON DELETE CASCADE ON UPDATE CASCADE 
);
