我有一张表，我们称它们为桌子 SUMMARYDATA

NIP  NAME   DEPARTMENT       STATUSIN           STATUSOUT             TOTALLOSTTIME 
------------------------------------------------------------------------------------------------
A1   ARIA   BB         2020-01-21 08:06:23  2020-01-21 11:58:36         00:23:15

我需要每月COUNT的记录where sum(TOTALLOSTIME) group by nip,name,department > 02:00:00并更新为table REPORTDATA，这是我的意思是一个示例输出：

DEPARTMENT     MONTH    YEAR   RTOTALLOSTTIME 
------------------------------------------------------------------------------------------------
  BB            01      2020           0              
  CC            01      2020           1

在数据类型列TOTALLOSTTIMEISnvarchar

到目前为止，这是我尝试过的：

select  MONTH(STATUSIN), YEAR(STATUSIN),NIP,NAME,DEPARTMENT,convert(varchar,dateadd(second,sum(datediff(second,'00:00:00',cast(TOTALLOSTTIME as time))),0),108) as sum_lost_time
from SUMMARYDATA b group by MONTH(STATUSIN), YEAR(STATUSIN),NIP,NAME,DEPARTMENT

该查询仅TOTALLOSTTIME在每个员工和每个月显示一次。
