Question

CREATE OR REPLACE TRIGGER btinsert
BEFORE INSERT ON sample
  BEGIN
    IF (TO_CHAR(SYSDATE,'HH24:MI')
          NOT BETWEEN ('08:00' AND '22:00') THEN 
    RAISE_APPLICATION_ERROR(-20500, 'you may insert'
       ||' into EMPLOYEES table only during '
       ||' normal business hours.'); 
   END IF;
END;

但是我收到了一个错误：

第8行的错误：PLS-00103：遇到符号“END”
  6. RAISE_APPLICATION_ERROR（-20500，'你可以插入'
  7. ||'只在'
期间进入EMPLOYEES表   8. ||'正常营业时间。'）;
  9.结束IF;
  10.结束;

你有一些缺失的括号和多余的括号。

CREATE OR REPLACE TRIGGER btinsert
BEFORE INSERT ON sample
  BEGIN
    IF (TO_CHAR(SYSDATE,'HH24:MI') NOT BETWEEN '08:00' AND '22:00') THEN 
    RAISE_APPLICATION_ERROR(-20500, 'you may insert'
       ||' into EMPLOYEES table only during '
       ||' normal business hours.'); 
   END IF;
END;

我试图在插入之前创建触发器但是会出现一些错误
