关于Oracle中的sql：右括号错误ORA-00907

right parenthesis error ORA-00907 in Oracle

我已经创建了这两个表。他们是员工超级类型的一部分。尝试在oracle中创建这些表时出现错误

ORA-00907: missing right parenthesis

我不确定为什么会收到此错误。谁能指出我的错误？

DROP TABLE Firstaiders;

CONSTRAINT pk_Firstaiders PRIMARY KEY (Staff_ID),

FOREIGN KEY(Staff_ID) REFERENCES Staff(Staff_ID) ON DELETE CASCADE ON UPDATE CASCADE

DROP TABLE Security;
CREATE TABLE Security(
Staff_ID NUMBER NOT NULL,
Security_ID NUMBER,
CRB_CHECK VARCHAR2(8),
fk1_Stage_ID NUMBER NOT NULL,

CONSTRAINT pk_Security PRIMARY KEY (Staff_ID),

FOREIGN KEY(Staff_ID) REFERENCES Staff(Staff_ID) ON DELETE CASCADE ON UPDATE CASCADE
);

删除Oracle不直接支持的ON UPDATE CASCADE。

例如：

CREATE TABLE Firstaiders(
Staff_ID NUMBER NOT NULL,
CONSTRAINT pk_Firstaiders PRIMARY KEY (Staff_ID),
FOREIGN KEY(Staff_ID) REFERENCES Staff(Staff_ID) ON DELETE CASCADE);

Oracle在ON DELETE CASCADE之后期望右括号，但是发现导致ORA-00907的ON UPDATE CASCADE
