更新彙總表

Question

我已經命名爲

PROD_DET 
(ID , PROD_SUMM_ID, TRANS_DATE, EMP_ID, PROC_ID , PCS) 

和

PROD_SUMM 
(ID , TRANS_DATE, EMP_ID, PROC_ID , PCS) 

現在，每當一個記錄插入PROD_DET表2桌，

我想Insert（如果唯一的TRANS_DATE，EMP_ID，PROC_ID的記錄不可用）/ Update（在記錄唯一的TRANS_DATE，EMP_ID，PROC_ID的情況下在我PROD_SUMM表可用），

1. 從PROD_DET獨特TRANS_DATE 表應放入PROD_SUMM表TRANS_DATE，

2. 獨特EMP_ID和獨特PROC_ID應該進入他們的 各列 在PROD_SUMM表

3. 的particluar TRANS_DATE的多個記錄PCS的總和應在 PCS列更新PROD_SUMM表
從PROD_SUMM表
4. ID應該 PROD_DET表

我已經嘗試了與觸發器，但升級到PROD_SUMM_ID列，並沒有來到大關， 在下面找到

看到粗糙work.any問題問。

Declare @tbl table([ID] [int] IDENTITY(1,1) NOT NULL,[TRAN_DATE] [date] NOT NULL,[EMP_ID] [int] NOT NULL,[PROC_ID] [int] NOT NULL,[PCS] [int] NOT NULL) 

insert into PROD_DET 
output inserted.TRANS_DATE, inserted.EMP_ID, inserted.PROC_ID , inserted.PCS into @tbl 
values() -- for PROD_DET 

merge PROD_SUMM as target 
using select id,b.TRAN_DATE,b.PCS,a.EMP_ID,a.PROC_ID from @tbl a inner join 
(select TRAN_DATE,sum(PCS) PCS from @tbl group by TRAN_DATE) b on a.TRAN_DATE=b.TRAN_DATE) as source 
on target.TRANS_DATE=source.TRANS_DATE and target.EMP_ID=source.EMP_ID and target.PROC_ID =source.EMP_ID 
when matched then 
update 
set TRAN_DATE=source.TRAN_DATE,EMP_ID=source.EMP_ID,PROC_ID=source.PROC_ID,PCS=source.PCS 
when not matched then 
insert (TRAN_DATE,EMP_ID,PROC_ID,PCS) 
values(source.TRAN_DATE,source.EMP_ID,source.PROC_ID,source.PCS)
