.You need to provide some more information on what data you have.
If you have a table with diagnosis and another table with there codes then a simple left join works.
data D_id;
infile datalines dlm=',' missover;
input id diagnosis $25.;
datalines;
101,mood disorders
102,sleep disorders
;
run;
data have;
infile datalines dlm=',' missover;
input patient diagnosis $25.;
datalines ;
1,mood disorders
2,mood disorders
3,sleep disorders
4,sleep disorders
;
run;
proc sql;
create table want as
select a.*,b.id
from have a
left join d_id b on a.diagnosis=b.diagnosis
;
quit;
Hi:
And, another approach is to use a FORMAT for a table lookup. In the example below, the PROC FORMAT was hardcoded, but you can build the format from a SAS dataset, too.
In this example, the value of the DIAGCODE variable will come from the $dgcode user defined format. This is another way to do a table lookup without doing a merge or a join.
