Hello all,
I am trying to replicate the attached SAS query in Impala. Basically, I want to pull all the observations from a dataset having a key variable "ID". Is there a way to replicate the same query using proc sql or may be in Impala.
data want;
if _n_=1 then do;
declare hash m(dataset:"keyvariable");
m.definekey('ID');
m.definedone();
end;
set have;
if m.find()=0;
run;
Thanks for your help,
Tom
