Question

我正在尝试执行if语句来确定employee_id，但是每次运行该程序时，都会不断出错。这是我与数据库交互的记录：

`enter code here`SQL> SET SERVEROUT ON FORMAT TRUNCATED
`enter code here`SQL> DECLARE
 `enter code here` 2
  `enter code here`3  EMP_REC HR.EMPLOYEES%ROWTYPE;
  `enter code here`4  BEGIN
  `enter code here`5  DBMS_OUTPUT.PUT_LINE ('---------------------------------------');
  `enter code here`6  FOR EMP_REC
  `enter code here`7  (SELECT *
  `enter code here`8  FROM HR.EMPLOYEES
  `enter code here`9  WHERE EMPLOYEE_ID = 5)
 `enter code here`10  LOOP
 `enter code here`11  IF
 `enter code here`12  IF (EMP_REC.EMPLOYEE_ID = 5) THEN
 `enter code here`13  DBMS_OUTPUT.PUT_LINE ('EMPLOYEE_ID: ' || EMP_REC.EMPLOYEE_ID) ;
`enter code here` 14  DBMS_OUTPUT.PUT_LINE ('FIRST_NAME: ' || EMP_REC.FIRST_NAME) ;
`enter code here` 15  DBMS_OUTPUT.PUT_LINE ('LAST_NAME: ' || EMP_REC.LAST_NAME) ;
`enter code here` 16  DBMS_OUTPUT.PUT_LINE ('SALARY: ' || TO_CHAR (EMP_REC.SALARY, '$999,999'));
`enter code here` 17  DBMS_OUTPUT.PUT_LINE ('---------------------------------------');
`enter code here` 18  END LOOP;
 `enter code here`19  END IF;
 `enter code here`20  EXCEPTION
 `enter code here`21  WHEN NO_DATA_FOUND THEN
 `enter code here`22  DBMS_OUTPUT.PUT_LINE ('NO DATA FOUND.');
 `enter code here`23
 `enter code here`24  END;
 `enter code here`25  /

这是正在报告的错误：

(SELECT *

您可以使用它来确定他们工作的部门，就像我们过去使用CASE所做的那样。如果他们赚了一定的钱，您可以用它来打印一条消息。如果在某个日期之前被雇用，也许他们应该加薪。
