如何从 table 和日期中获取一个顶级数字 ID

Question

我有这个代码：

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

结果如下：

我想每个 part_id

只有一个 base_id

Answer 1

试试这个。根据您的解释假设这一点。

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

已根据您的新查询更新...试试这个。假设 SQL 服务器。

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
