如何使用 Where 而不是 Group by？

Question

我写了一个查询，给了我这个 Output：

（这只是一个示例，显然 Output 表大约包含 300000 行）

这是我的查询：

  proc sql;
  create Table Output as 
  select ID_User, Division_ID, sum(conta) as Tot_Items, max(Counts) as Max_Item
  from (select c.ID_User , c.Div_ID as Division_ID, ro.code as Mat, count(*) as Counts
  from Ods.R_Ordini o
  inner join DMC.Cust_Dupl c
   on User_ID = ID_User
  inner join ods.R_Nlines ro
   on ro.Orders_Id = o.Id_Orders AND RO.SERVICE = 0
  inner join ods.R_Mat m
   on ro.Mat_Id = Id_Mat and flag = 0
  group by 
      ID_User,
      C.Division_ID,
      Ro.Code
      Having Counts > 1
     )
  group by
  Id_User,
  Division_ID
  Order by 
  Tot_Item DESC
  ;
  quit;

所以，我想要的是重新编写这个查询，但我想使用 Where 条件而不是 Group by，(WHERE=(DIVISION_ID=3)) 这是条件。

我尝试了几次，有一些我出错了，还有一些我确实得到了 output，但 output 和原来的不一样。

任何帮助将不胜感激，谢谢。

Answer 1

SAS 数据集选项(where=(<where-expression>))只能与数据集名称相邻编码。 因此，该选项必须应用于包含列div_id的数据集，该列是计算列division_id的基础。 那将是表别名c

DMC.Cust_Dupl(where=(div_id=3)) as c

或者只使用普通的 SQL where 子句

…
)
where division_id=3
group by … 

Answer 2

只需在 group by 之前使用 WHERE DIVISION_ID=3 。

select ID_User, Division_ID, sum(conta) as Tot_Items, max(Counts) as Max_Item from (select c.ID_User, c.Div_ID as Division_ID, ro.code as Mat, count(*) as Counts from Ods.R_Ordini o inner join DMC.Cust_Dupl c on User_ID = ID_User 内部连接 ods.R_Nlines ro on ro.Orders_Id = o.Id_Orders AND RO.SERVICE = 0 内部连接 ods.R_Mat m on ro.Mat_Id = Id_Mat 和 flag = 0 WHERE DIVISION_ID ID_User, C.Division_ID, Ro.Code 计数 > 1) 按 Id_User 分组, Division_ID 按 Tot_Item 排序 DESC
