早上好,我这个问题。
有2个数据集
数据集“ID用户”在那里我有这样的:
id | Customer Name |
-----------------------------
123456 | Michael One |
123123 | George Two |
123789 | James Three |
而第二个数据集命名为“交易”:
id | Transaction | Date
-----------------------------------
123456 | Fuel | 01NOV2018
123456 | Fuel | 03NOV2018
123123 | Fuel | 10NOV2018
123456 | Fuel | 25NOV2018
123123 | Fuel | 13NOV2018
123456 | Fuel | 10DEC2018
123789 | Fuel | 1NOV2018
123123 | Fuel | 30NOV2018
123789 | Fuel | 15DEC2018
我想要的结果是创造3分贝像3客户ID,我在指定的第一个数据集已经:
_01NOV2018_15NOV_123456_F
_01NOV2018_15NOV_123123_F
_01NOV2018_15NOV_123789_F
包含:
For _01NOV2018_15NOV_123456_F :
id | Transaction | Date
-----------------------------------
123456 | Fuel | 01NOV2018
123456 | Fuel | 03NOV2018
For _01NOV2018_15NOV_123123_F :
id | Transaction | Date
-----------------------------------
123123 | Fuel | 10NOV2018
123123 | Fuel | 13NOV2018
For _01NOV2018_15NOV_123789_F
empty
我需要创建一个变量数据的步骤,其中一个条款...我怎样才能使这个?
感谢帮助! :)`
该HASH
OUTPUT
方法是创建在DATA步骤运行时动态命名输出数据集的唯一途径。每个问题的评论,你很可能不希望你的原始数据集分成很多内容命名件。无论如何,如过程,在SAS,被称为分割。
你是远更好的服务学习如何在这两个数据步应用WHERE
声明和BY
组处理,并PROC步骤。
想要的输出似乎被隔离或基于半一个月分类。你可能通过计算含有适当分类值的新semimonth
变量,然后使用该下游,例如在PROC PRINT
来提供最好的服务。

你可以通过你的PROC出口代号小宏或只是一个快速过滤器做到这一点。
proc export data=sashelp.class (where=(sex='F')) outfile='/folders/myfolders/females.xlsx' dbms=xlsx replace; run;
proc export data=sashelp.class (where=(sex='M')) outfile='/folders/myfolders/females.xlsx' dbms=xlsx replace; run;
或者你也可以将此转换为小宏:
%macro exportData(group=);
proc export data=sashelp.class (where=(sex="&group."))
outfile="C:\_localdata\&group..xlsx"
dbms=xlsx
replace;
run;
%mend;
*create list of unique elements to call the macro;
proc sort data=sashelp.class nodupkey out=class;
by sex;
run;
*call the macro once for each group;
data test;
set class;
str = catt('%exportData(group=', sex, ');');
call execute(str);
run;
