Hello everyone ,

last week I worked with one datasets and I kept the variables that I need and it's ok . Today I need another var in other dataset , :

this is my first data

libname data "X:\blabla \data\";

PROC IMPORT OUT= WORK.myfile

DATAFILE= "X:\blabla \data\Stata datasets\data1"

DBMS=STATA REPLACE;

RUN;

and I want work with dataset 2, is it correct the following command ?

libname data "X:\blabla \data\";

PROC IMPORT OUT= WORK.myfile

DATAFILE= "X:\blabla \data\Stata datasets\data1"

DBMS=STATA REPLACE;

DATAFILE= "X:\blabla \data\Stata datasets\data2"

DBMS=STATA REPLACE;

RUN;

You can find the documentation of proc import in Base SAS(R) 9.4 Procedures Guide, Second Edition. If you don't like reading docs simple execute the proc and see what SAS has to say

I don't know about STATA files but in many cases you can use a FILENAME statement to associate multiple files and read them.

Question: You have one output file and two input, are you wanting to have the data from the two STATA files combined into a single SAS data set?

You want to combine the variable from the new file with the variable from the old file then you want to do some type of merge.

If you have a simple file with a unique id variable then a data step merge will do the trick.

libname data "X:\blabla \data\";

PROC IMPORT OUT= WORK.myfile

DATAFILE= "X:\blabla \data\Stata datasets\data1"

DBMS=STATA REPLACE;

RUN;

PROC IMPORT OUT= WORK.myfile2

DATAFILE= "X:\blabla \data\Stata datasets\data2"

DBMS=STATA REPLACE;

RUN;

data want;

merge myfile myfile2;

by ID ;

run;
