SAS : Run SAS Procedure on Multiple Datasets

This tutorial explains how to run SAS procedure on multiple datasets.

Dictionary.Columns vs. Dictionary.Tables

See the comparison between Dictionary.Columns and Dictionary.Tables in SAS.

Dictionary.Columns

It returns information about the columns in one or more data sets. It is similar to the results of the CONTENTS procedure.

Dictionary.Tables

It returns information about names of SAS files and type, date created and last modified, number of observations, observation length, number of variables etc.

Count Number of Datasets in a library

The following code counts the number of tables in the specified library (sashelp) using the dictionary.tables view and store the count in the macro variable "n". The value of n is then printed to the SAS log using the %put statement.

%let lib = sashelp;
proc sql noprint;
select count(*) into :n
from dictionary.tables
where libname=%upcase("&lib");
quit;
%put &n;

List name of all datasets in a SAS library

The following code returns a list of table names from a specified library (sashelp) and then store each table name in separate macro variables using a range of macro variable names. The number of macro variables created would be equal to the number of tables in the library.

proc sql noprint;
select memname into :data1 - :data%LEFT(&n)
from dictionary.tables
where libname=%upcase("&lib");
quit;

Export all SAS data sets of a library in CSV format

The following SAS macro named "temp" exports data from multiple tables in a specified library to CSV files.

%macro temp;
%do i=1 %to &n.;
proc export data = &lib..&&data&i
outfile = "C:\Users\Deepanshu\Documents\KeyBank\&&data&i...csv"
DBMS = CSV;
run;
%end;
%mend;
%temp;
