This tutorial explains how to run SAS procedure on multiple datasets.
See the comparison between Dictionary.Columns and Dictionary.Tables in SAS.
Dictionary.ColumnsIt 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.
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;
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;
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;

Awesome concepts!!! Thanks
ReplyDeleteHi Deepanshu
ReplyDeletei want to print all table names. Written below code
%let lib = sashelp;
proc sql noprint;
select memname into :data1 - :data10
from dictionary.tables
where libname=%upcase("&lib");
quit;
%macro mymacro;
%do i=1 %to 10;
%put &data&i;
%end;
%mend;
%mymacro;
getting error:
WARNING: Apparent symbolic reference DATA not resolved.
&data1
WARNING: Apparent symbolic reference DATA not resolved.
&data2
WARNING: Apparent symbolic reference DATA not resolved.... so on
Please suggest
Please use "&&data&i" inside the %do loop
DeleteThen 10 dataset names will be shown in the log
related to previous above post....
ReplyDeletegot resolved by &&data&i
still have query that how n value is identified in below code
%do i=1 %to &n.;
hello,
ReplyDeletewhy we have used "..." in "&&data&i...CSV" statement?
shouldn't line 8 be %put &n.;
ReplyDeleteHi, how can we loop over all sas datasets in our work library and add the table name as a column in all datasets? All the file names are different.
