The following code I wrote before is to check the variable with all the missing value under WORK library 's all tables.
a.k.a It print the variable name which value are all missing.
%let library=work; /*Here is the library I want to search*/
%macro find_missing_var(dsn);
proc transpose data=&dsn(obs=0) out=vname;
var _all_;
run;
proc sql noprint;
select catx(' ','n(',_name_,') as',_name_) into :vnames separated by ','
from vname;
create table temp as
select &vnames from &dsn;
quit;
proc transpose data=temp out=temp1;
var _all_;
run;
data temp2;
length table_name _name_ $ 100;
table_name="&dsn";
set temp1;
if col1=0;
run;
proc append base=want data=temp2 force;
run;
%mend;
proc delete data=want;
run;
data _null_;
set sashelp.vtable(
keep=libname memname
where=(libname="%upcase(&library)")
);
call execute(cats('%nrstr(%find_missing_var(',libname,'.',memname,'))'));
run;
title 'COLUMNS WITHOUT DATA';
proc print;
run;
