data output; set datarolling_ETFS; if rankdate < '20050630'YYMMDDN8. then delete; run;
I have problem to define the format date
Edit by KB: Formatted code and put it in correct window.
The answer depends on what your variable actually contains.
It is a true SAS date? Then use:
if rankdate < '30Jun2005'd then delete;
Is it a six-digit number? Then use:
if rankdate < 20050630 then delete;
Is it a character variable of some sort? Then use:
if input(rankdate, 6.) < 20050630 then delete;
But you need to understand some basic information about what is in your variable to select the proper answer.
To keep the ymd date format, use the input() function:
data output; set datarolling_ETFS; if rankdate < input('20050630',YYMMDD8.) then delete; run;
