How to import multiple sas datasets into sas conditionally

ssv — Wed, 11 Apr 2018 04:26:07 GMT

Hi there!

I have to import few datasets(sas7bdat) from external source into SAS. so I have used libname statement to address those datasets location. Is there any way to copy each of these datasets in to new datasets conditionally?

FOR EXAMPLE: I have 5 sas datasets (a, b, c, d, e with extension .sas7bdat) in C:\Users\Desktop\XYZ folder. i have used this LIBNAME Statement to import them into sas.

LIBNAME IMPORTED "C:\Users\Desktop\XYZ";

I want to copy these datasets(A, B, C, D, E) into 5 NEW datasets(P, Q, R, S, T) conditionally, which means I want to copy dataset A into P, B into Q, C into R, D into S, E into T.

I am doing this:

Data P;

set A;

run;

data Q;

set B;

run;

But is there any possibility of reducing the code? instead of using the set statement and repeating the code again and again is there any other way?

Your response is Highly Appreciated.

Thank you.

If you keep the same name, you can use proc copy (and a select statement if needed).

Copy the files into a new folder. Keeping source and target clearly separated is "cleaner" and it also allows you to use Proc Datasets.

options dlcreatedir;

libname source 'c:\temp\source';
data source.a;
  set sashelp.class;
run;

data source.b;
  set sashelp.class;
run;

libname target 'c:\temp\target';
proc datasets lib=target nolist;
  delete p q;
  run;
  copy in=source out=target;
    select a b;
  run;
  change a=p b=q;
  run;
quit;

PROC DATASETS/COPY moves the data over in chunks, a data step copies the data line by line. This means PROC COPY is significantly faster as well.
