如何從一個表和日期

Question

得到一個頂級的數字ID我有這樣的代碼：

SELECT TYPE, BASE_ID, PART_ID, CREATE_DATE 
FROM WORK_ORDER 
WHERE CREATE_DATE >'17-NOV-2016' AND WAREHOUSE_ID ='MEX-04' 

，並讓作爲結果：

我想有隻base_id每part_id之一

Answer 1

試試這個。從你的解釋中假設這一點。

SELECT TYPE, Max(BASE_ID) BASE_ID, PART_ID, CREATE_DATE 
FROM WORK_ORDER 
WHERE CREATE_DATE >'17-NOV-2016' AND WAREHOUSE_ID ='MEX-04' 
Group By Type, Part_ID, Create_Date 

更新根據新的查詢......試試這個。假設SQL Server。

SELECT PART.ID ,PART.USER_10 ,PART.USER_1 ,WORK_ORDER.STATUS 
,SUM (CASE when (OPERATION.RESOURCE_ID = '121-ADD') THEN OPERATION.RUN ELSE 0 END) "121-ADD" 
FROM PART 
JOIN WORK_ORDER ON PART.ID = WORK_ORDER.PART_ID 
JOIN OPERATION ON WORK_ORDER.PART_ID = OPERATION.WORKORDER_BASE_ID 
Where 
OPERATION.WORKORDER_TYPE ='M' 
AND --(NewCode here) 
OPERATION.RUN >0 AND WORK_ORDER.WAREHOUSE_ID ='MEX-04' 
AND WORK_ORDER.TYPE ='W' AND PART.FABRICATED ='Y' 
AND WORK_ORDER.CREATE_DATE >'17-NOV-2016' 
GROUP BY PART.ID ,PART.USER_10 ,PART.USER_1 ,WORK_ORDER.STATUS
