Hi!
I want to add new column to datasetA from another dataset(datasetB) in one step.
NOTE:
There’s no variable for merge.
From my google search,below information is hit,especially its title is so nice.
Adding One Value to All Records in a SAS® Data Set
But there’s no way for “by 1 step” or “in a data step”.
By now,I think “proc sql with alter” have possibility for it.
Or we can’t do it?
Because SAS’s help page for "alter" don’t have a example for it.
SAS help page of "alter in proc sql"
Someone please help me.
I introduce what I want to do with "2 step".
data work.datasetB;
var1="add this value for all obs";
output;
run;
data work.datasetA;
key=1;output;
key=2;output;
key=3;output;
run;
/* 1step */
data _null_ ;
set datasetB;
call symputx ('var1_value', var1) ;
run ;
/* 2step */
data work.datasetA;
set work.datasetA;
val1="&var1_value";
run;
Result
proc sql;
create table want as
select datasetA.*, datasetB.*
from dataset A, datasetB;
quit;
