新手求教。。

There are four coding errors in this statement. Can you identify them?
SELECT employee_id, last_name
sal x 12 ANNUAL SALARY
FROM employees;


这段语句怎么修改？

谢谢

SELECT employee_id, last_name
sal x 12 "ANNUAL SALARY"
FROM employees;

:'(:'(ths!!!

sal * 12 "ANNUAL SALARY"
    *

ERROR 位于第 2 行:
ORA-00923: 未找到预期 FROM 关键字

报错阿。。。

SELECT employee_id, last_name ,
sal*12 "ANNUAL SALARY"
FROM employees;
可以吗？

SELECT employee_id, last_name,
SALARY*12  "ANNUAL SALARY" FROM employees;

可以了。。。谢谢啊！！！:'(:'(:victory::kiss:
