Hi,
I wonder if anyone has an answer to Oracles LISTAGG function for SAS?
I'm using base SAS programming 7.1 & need some examples if anyone can help.
I've seen some examples using the 'BY' process.
Does anyone have any clear examples?
Thanks
SAS doesn't have summary functions for strings, sadly.
So you'll have to code it. For example:
data CLASS (index=(SEX));
set SASHELP.CLASS;
run;
data T;
length NAMES $200;
retain NAMES;
set CLASS;
by SEX;
if first.SEX then NAMES='';
NAMES=catx(',',NAMES, NAME) ;
if last.SEX then putlog NAMES=;
run;
NAMES=Alice,Barbara,Carol,Jane,Janet,Joyce,Judy,Louise,Mary
NAMES=Alfred,Henry,James,Jeffrey,John,Philip,Robert,Ronald,Thomas,William
