Hi all,
if I have a set of id's in table A(a subset of table B) and an tring to create a new dataset from table B. Is it possible to make a reference between the two tables (I want to make a selection depending on the pat_id's in table A)
for a examples using the code below:
For example if table A conains the following Dataset
pat_id
1
2
3
and table B contains
pat_id var1 var2
1 35 3.5
2 77 6.7
3 15 5.3
4 11 2.0
5 1.2
6 54 8.9
proc sql; create table dataset_new as select var1, var2 from tableB where pat_id in tableA; quit;
Use a sub-query:
data table_a;
input pat_id;
datalines;
1
2
3
;
run;
data table_b;
input pat_id var1 var2;
datalines;
1 35 3.5
2 77 6.7
3 15 5.3
4 11 2.0
5 . 1.2

;
run;
proc sql;
create table want as
select
*
from
table_b
where
pat_id in (
select
pat_id
from
table_a )
;
quit;
Obs pat_id var1 var2 1 1 35 3.5 2 2 77 6.7 3 3 15 5.3
