hello am trying access columns from library with specific date format and using year function on the columns in my macro code but it produces duplicate values... but the year function displays duplicate values and does not provide desired results. my code should return only the year from the input dates.
%macro dteyear(lib=,outdsn=);
proc sql noprint;
select distinct catx(".",libname,memname), name
into :dsns separated by " ", :varname separated by " "
from dictionary.columns
where libname = upcase("&lib") and format=('YYMMDD10.')
order by 1;
quit;
%put &dsns;
%put &varname;
%local olddsn curdsn curvbl i;
data &outdsn.;
set
%let olddsn=;
%do i=1 %to &sqlobs;
%let curdsn=%scan(&dsns,&i,%str( ));
%let curvbl=%scan(&varname,&i,%str( ));
%if &curdsn NE &olddsn
%then %do;
%if &olddsn NE
%then %do;
)
%end;
%let olddsn=&curdsn.;
&curdsn (keep=&curvbl
%end;
%else %do;
&curvbl
%end;
%end;
);
%do i=1 %to &sqlobs;
%scan(&varname,&i,%str( ))=year(&varname.);
%end;
run;
proc print data=&outdsn;run;
%MEND;
%dteyear(lib=dte3,outdsn=dtetst);
the input data is as follows
1975-12-04
1977-11-03
1989-09-15
1998-06-17
1999-05-31
2000-08-14
2001-03-11
2007-03-11
2007-12-28
2008-10-07
2009-12-03
duplicate output from my code is-->

The basic problem is that the
YEAR()
function returns a 4-digit number, and the variable's format is YYMMDD10., so the result is formatted as a SAS date very close to 1960 (SAS's beginning of all time).What I did in the code below was change the format to 4.0, so it displays as a 4-digit number.
If you want to have access to the original date variable, you'll have to create a new variable for the year. I'll leave that to you.
There was an additional problem--that is,
YEAR(&varname.)
inserts the entire list of variables, not just the one you're working with. It works if there is only one date variable, but not if there are more than one. I fixed this, too.The result, then, is:
