Oracle Homework - SQL语句错误

Question

我收到错误ORA-00936：在以下SQL语句中缺少表达式：

SELECT || first_name || ' ' || last_name || AS "Possible Candidates"
from EMPLOYEES
WHERE LAST_NAME LIKE '%s';

我正在尝试获取名字和姓氏，并将其显示在一个名为“可能的候选人”的列中，其中姓氏的最后一个字母是“s”。

谢谢！

SELECT first_name || ' ' || last_name AS "Possible Candidates"
from EMPLOYEES
WHERE LAST_NAME LIKE '%s';
