SQL Server更新与左连接和组通过

Question

我正在更新我们的数据库，并想要更新没有在另一个表中的现有项目的行。我可以一起加入表格，但是无法将表格分组以获得行数

UPDATE dpt 
SET dpt.active = 0 
FROM DEPARTMENT dpt 
LEFT JOIN DOCUMENTS doc on dpt.ID = doc.DepartmentID 
GROUP BY dpt.ID 
HAVING COUNT(doc.ID) = 0 

我该怎么做？

        FROM DOCUMENTS doc 
        WHERE doc.departmentid = id)

     FROM doc 
     )
