BEGIN 

FOR EMP_REC IN EMP_CURSOR 
WHILE EMP_REC%FOUND 

    LOOP 
     IF EMP_REC.SALARY > 10000 AND EMP_REC.DATE_HIRE< DATE '2000-01-01' 
     THEN 
     DBMS_OUTPUT.PUT_LINE (EMP_REC.EMPLOYEE_NAME || ' earns ' || EMP_REC.SALARY || 'and joined the organization    on ' || EMP_REC.DATE_HIRE); 
     END IF;

試試這個：

DECLARE 

    CURSOR EMP_CURSOR IS SELECT EMPLOYEE_NAME, SALARY, DATE_HIRE FROM EMPLOYEES WHERE DEPARTMENT_ID=1; 

BEGIN 

FOR EMP_REC IN EMP_CURSOR 

    LOOP 
     IF EMP_REC.SALARY > 10000 AND EMP_REC.DATE_HIRE< DATE '2000-01-01' 
     THEN 
     DBMS_OUTPUT.PUT_LINE (EMP_REC.EMPLOYEE_NAME || ' earns ' || EMP_REC.SALARY || 'and joined the organization    on ' || EMP_REC.DATE_HIRE); 
     END IF; 
    END LOOP; 

END;
