I am trying to read a date column in sas from csv file but it gives some error:
error: NOTE: Invalid argument to function INPUT at line 2134 column 11
Appreciate any help to resolve this issue. Thanks
data:
have:
id date
1 27-Apr-12
2 03APR2013
3 11-Mar-13
4 01-Jun-12
my code:
data want;
set have;
format date date9.;
date=upcase(date);
if not missing(date) then do;
lbdt=input(date, ddmmyy9.);
end;
run;
SAS offers generic date formats such as ANYDTDTE. to handle this kind of poor quality data. Try:
data have;
input id date :$20.;
datalines;
1 27-Apr-12
2 03APR2013
3 11-Mar-13
4 01-Jun-12
;
data want;
set have;
d = input(date, ?? anydtdte.);
format d yymmdd10.;
drop date;
rename d=date;
run;
proc print; run;
Simple answer, clean your data. 27-Apr-12 is not the same as 27APR2012 or in fact 20120427. What if you have dates in US format:
02012012 - is this 02Jan or 01Feb? Garbage data will 90% of the time yield garbage results.
And a secondary note, CSV is not Excel, CSV=Comam Separated Variable file, which is a plain text file with commas separating data elements. The fact that Excel has a parser for that doesn't make it an Excel file.
data have;
input id date : date11.;
format date date9.;
datalines;
1 27-Apr-12
2 03APR2013
3 11-Mar-13
4 01-Jun-12
