SQL查询leftjoin怎么写？

Question

和table这样我要回答：

给定 Employee 和 AnnualReviews table，向 return 所有从未接受过按 HireDate 排序的评论的员工编写查询。（下图Tablelink）

这是我的疑问，请帮助更正：

Select

LastName,
FirstName

from Employee a leftjoin AnnualReviews b ON a.`ID` = b.`EmpID`
where HireDate desc

Group by
ID

[员工与年度回顾][1]

[1]: employee & annual review table

Answer 1

SELECT * FROM employee
WHERE terminationdate IS NULL AND lastname LIKE ‘SMITH%’
ORDER BY lastname, firstname;
