HI, All:
I have a SAS data where a date column is a mixture of Date and date/time, and the column is a string. the column looks like below:
1/4/2017 1/31/2017 1/10/20176:18:22AM 1/10/201712:18:28AM 1/3/201711:08:58AM 1/3/201711:9:1AM 1/30/20177:53:21AM |
I want to seperate only the mm/dd/yy information from the string. All the year are 2017, is that possible to use 2017 as a delimiter to get MM/DD/YYYY from the strings? How to do it?
You can do it by:
data want;
infile cards;
input dtime $;
date_part = substr(dtime,1,index(dtime,'2017')+3);
date_in = input(date_part, ddmmyy10.);
cards;
1/4/2017
1/31/2017
1/10/20176:18:22AM
1/10/201712:18:28AM
1/3/201711:08:58AM
1/3/201711:9:1AM
1/30/20177:53:21AM
; run;

Thank you very much. Finally i can get the date out.
Here is one way:
data want; input @; sub=index(_infile_,'2017')+3; _infile_=substr(_infile_,1,sub); input date : mmddyy10.; format date date9.; cards; 1/4/2017 1/31/2017 1/10/20176:18:22AM 1/10/201712:18:28AM 1/3/201711:08:58AM 1/3/201711:9:1AM 1/30/20177:53:21AM ;

thank you. it help me to pull the date out from the long string.
There's probably many ways to do this, but this is what I'd to to get the date and time extracted.
data dates;
format date mmddyy. time timeampm.;
input @1 dateTxt $32.;
dateTxt = prxchange('s/2017/2017~/', 1, dateTxt);
date = input(scan(dateTxt, 1, '~'), mmddyy10.);
time = input(scan(dateTxt, 2, '~'), time10.);
datalines;
1/4/2017

;
alternatively with call prxsubstr
data dates;
format date mmddyy. time timeampm.;
input @1 dateTxt $32.;
prxid=prxparse('/\d{1,2}\/\d{1,2}\/\d{2,4}/');
call prxsubstr(prxid,datetxt,start,length);
date=input(substr(dateTxt,start,length),mmddyy10.);
time=input(substr(dateTxt,length+1),time.);
datalines;
