ORACLE - 缺少關鍵字生成表幫助

Question

當我試圖完成一個項目，但我不斷收到「缺少關鍵字」錯誤，當我嘗試創建一個表：

CREATE TABLE SKILLS (
SkillsID CHAR(4) NOT NULL, 
ConsultantID CHAR(4) NOT NULL, 
ExpertiseID CHAR(4) NOT NULL, 
MonthsExperience INT NOT NULL, 

CONSTRAINT SkillsPK PRIMARY KEY (SkillsID), 

CONSTRAINT SkillsConsultFK FOREIGN KEY(ConsultantID) 
       REFERENCES CONSULTANTS(ConsultantID) 
       ON UPDATE NO ACTION     
       ON DELETE CASCADE, 


CONSTRAINT SkillsExpertiseFK FOREIGN KEY(ExpertiseID) 
       REFERENCES EXPERTISE(ExpertiseID) 
       ON UPDATE NO ACTION 
       ON DELETE CASCADE 
) 

請！所有幫助非常感謝

Answer 1

刪除ON UPDATE NO ACTION。由於Oracle中沒有ON UPDATE CASCADE，因此不需要指定NO ACTION。
