HH_NO | X |
---|---|
01 | 9 |
01 | 3 |
02 | 9 |
03 | 1 |
03 | 2 |
I have a similar dataset but with more rows. I want to select all the HH_NO that do NOT have any X=9, like HH_NO=03
How do I do so?
Thank you
Many ways to this. SQL with a subquery (inner join or where) are two.
As Linush said,there are many ways to do this,
Here is one of the way,
Data test;
input a b ;
cards;
01 9
01 3
02 9
03 1
03 2
run;
Proc Sql;
select Distinct a into :value separated by ' ' from test
where b eq 9;
quit;
Data final;
set test;
if a not in (&value);
run;
Proc print;
run;
One more way,
Data test;
input a b ;
cards;
01 9
01 3
02 9
03 1
03 2
run;
Proc Sql;
select A,b from test
where a not in (Select distinct a from test where b eq 9);
quit;
Thanks,
