I am trying to merge and create new records.
However with following code, the records for new2 are not output.
I want records for new1 and new2 in the final data based on the conditions.
Any solutions ? or may be sql alternative ?
Thanks.
data d1 ;
input VISIT PARAMCD $3-10 PATHOGEN $11-13 subject $14-16;
datalines ;
10 param3 P1 1
40 param1 P2 1
40 param3 P2 1
40 param2 P2 1
10 param1 P2 2
10 param3 P2 2
10 param2 P2 2
40 param1 P3 3
40 param3 P3 3
40 param2 P3 3
;
run;
Data param1 param2 param3 ;
set d1 ;
if paramcd='param1' then output param1 ;
if paramcd='param2' then output param2 ;
if paramcd='param3' then output param3 ;
drop paramcd ;
run ;
data d2 ;
merge d1 (in=a where= (visit ne . ))
param1 (in=param1 )
param2 (in=param2 )
param3 (in=param3 )
;by subject visit pathogen ;
if paramcd='param1' and param2 then do ; paramcd= 'new1' ; output ;end;
if paramcd='param1' and param3 then do ; paramcd= 'new2' ; output ;end;
Run;
Please look at the result from this code:
data d2 ; merge d1 (in=a where= (visit ne . )) param1 (in=param1 ) param2 (in=param2 ) param3 (in=param3 ) ;by subject visit pathogen ; if paramcd='param1' and param2 then do ; paramcdnew= 'new1' ; output ;end; if paramcd='param1' and param3 then do ; paramcdnew= 'new2' ; output ;end; Run;
At least with your example data, if I understand what you are attempting, when you set Paramcd to 'new1' the value is no longer there for use in the second IF.
Try this: Test the Paramcd value only one time.
data d2 ; merge d1 (in=a where= (visit ne . )) param1 (in=param1 ) param2 (in=param2 ) param3 (in=param3 ) ;by subject visit pathogen ; if paramcd='param1' Then do; if param2 then do ; paramcd= 'new1' ; output ;end; if param3 then do ; paramcd= 'new2' ; output ;end; end; Run;
Seems you have an issue with the logic and you dropped the column paramcd, so i have modified code and included below.

40 param1 P2 1

40 param2 P2 1
10 param1 P2 2
10 param3 P2 2
10 param2 P2 2
40 param1 P3 3
40 param3 P3 3
40 param2 P3 3

merge d1 (in=a where= (visit ne . ))
param1 (in=param1 )

@ballardw This worked. Thanks. Also changed the output var name.
