Question

 CREATE OR REPLACE TRIGGER log_FAMILY_increase
  AFTER UPDATE OF FAMILY_INCOME ON STUDENT
  FOR EACH ROW
 BEGIN
   INSERT INTO STUDENT_2 (NAME, SURNAME, NEW_FAMILY_INCOME)
   VALUES (:NEW.NAME,SURNAME, :NEW.FAMILY_INCOME, 'New INCOME');
 END;

在oracle 10g中我收到此错误消息：第2行的错误：PL / SQL：忽略语句

Answer 1

你在这里错过了一个列名“(name, surname, new_family_income)”，因为你试图将4个值插入3列。我切换了语句，没有列出列，也许这会有所帮助..

CREATE OR REPLACE TRIGGER log_family_increase
   AFTER UPDATE OF family_income
   ON student
   REFERENCING NEW AS new OLD AS old
   FOR EACH ROW
BEGIN
   INSERT INTO student_2 
        VALUES (:new.name,
                :new.surname,
                :new.family_income,
                'New INCOME');
END;

第2行的错误：PL / SQL：语句被忽略
