Hi Im importing csv file to via the web interface but SAS recognized my date column as VARCHAR not as Date type. Can someone assist me or provide something to read/ learn on how to import Date type of data to the environment.
It looks like from the values in the photograph at the end of your post don't have date strings at all. Do you want to make DATE values (number of days) from those strings or DATETIME values (number of seconds)?
Either way you cannot convert the existing character variable DATE into a numeric variable that could be used to store either DATE or DATETIME values. You need to make a NEW variable (you can always rename them if you really like the name, but I recommend to not name the variable DATE if you are going to populate it with DATETIME values).
It is hard to tell from those examples how to interpret the beginning of those strings as representing dates. Are they in DMY order? MDY order? YMD order? Is that first value to first of june in 2020? Or perhaps first of june in 1920? Or is it the January sixth? Or perhaps it is 20JUN2001? Or 20JUN1901?
Make sure to use an informat that appropriate for the values you have.
Make sure to attach a format to your new date or datetime values so they display in a human readable way.
data datauncertaintytestnew;
set test.datauncertaintytest(rename=(date=date_string));
date = input(scan(date_string,1,' '),mmddyy10.);
datetime = input(date_string,anydtdtm20.);
format date date9. datetime datetime20.;
run;
Please post a sample lines of your csv file to show the exact format of date input.
In general, in case like you described, read the data into a temporary char type variable then use function input to convert it to a numeric variable with appropriate format as in next example:
datex = "03DEC2020:00:00:00";
date = input(datex,daytime18.);
The line
date = input(Date,date.9);
cannot be used with a procedure but in a sas data step only.
after running proc contents:
PROC CONTENTS DATA=WORK.IMPORT; run;
check what type is date variable - is it CHAR type or NUM type.
Please post an example of a date value you got. You can do it by
proc print data=work.import(obs=3); /* 3 observations are enough */
var date; /* add any variable you want to reformat */
run;
the next step depends on type and values of your imported dataset.
cas mysess sessopts= (caslib=casuser);
libname test cas caslib=casuser;
proc print data=test.datauncertaintytest(obs=3);
var Date;
run;
data datauncertaintytestnew;
set test.datauncertaintytest;
date = input(Date,date13.);
run;
This is the code that I have run, but I still can't manage to convert it to date type. Below is the warning message appear whenever I try to run the code.

Thank you for your response!!!
It looks like from the values in the photograph at the end of your post don't have date strings at all. Do you want to make DATE values (number of days) from those strings or DATETIME values (number of seconds)?
Either way you cannot convert the existing character variable DATE into a numeric variable that could be used to store either DATE or DATETIME values. You need to make a NEW variable (you can always rename them if you really like the name, but I recommend to not name the variable DATE if you are going to populate it with DATETIME values).
It is hard to tell from those examples how to interpret the beginning of those strings as representing dates. Are they in DMY order? MDY order? YMD order? Is that first value to first of june in 2020? Or perhaps first of june in 1920? Or is it the January sixth? Or perhaps it is 20JUN2001? Or 20JUN1901?
Make sure to use an informat that appropriate for the values you have.
Make sure to attach a format to your new date or datetime values so they display in a human readable way.
