我有一个大型SAS数据表，其中包含一系列针对我的整个基本客户群的指标（Master_v01）。我有一个单独的数据表，其中包含我想从分析中排除的客户列表（Excluded_Cust）。
是否可以做这样的事情：
data Master_v02;
set Master_v01;
where cust not in (select cust from Excluded_Cust);
run;
这可能吗？
如果没有，那么实现我想要的目标的最佳方法是什么，将我想要排除的客户的基本表从数据中删除？

答案 1 :(得分：0)
我的数据步骤代码有点生疏，但您可以通过查找值并检查匹配来执行此操作。我认为这就是：
data Master_v02;
set Master_v01;
set Excluded_Cust key=cust;
if _iorc_ = 0 then delete;
run;
当然，建议cust中的Excluded_Cust索引。
答案 2 :(得分：0)
我能想到的两种方法：
1.PROC SQL
proc sql;
create table Master_v02 as
select *
from Master_v01
where cust not in (select cust from Excluded_cust);
quit;
2.DATA STEP MERGE
首先按cust排序Master_V01和Excluded_cust数据集，然后：
data Master_V02;
merge Master_V01 (in=Mast)
Excluded_cust (in=Excl);
by cust;
if Mast and not Excl;
run;
