Invalid date/time constant

[luvscandy27]

Hello all, I am working with the code below and I keep getting the error. ERROR: Invalid date/time/datetime constant "stdft."d. I have checked my 

formats and they are all the same and I just can't seem to figure out what is causing the error? 

data dates;
 infile datalines delimiter = ',';
 input ID $ DATE:anydtdte11. COND STDT:anydtdte11. ENDT:anydtdte11. ;
 format  date stdt endt mmddyy10.;
 datalines;
1,  05/03/2018, .,    05/03/2017, 05/03/2018
1,  05/02/2018, .,   05/02/2017, 05/03/2018
2,  04/26/2018, 1,    04/26/2017, 04/27/2018
2,  04/18/2018, 1,    04/18/2017, 04/18/2018
2,  04/10/2018,  1,  04/10/2017, 04/10/2018
;
run;

proc sql; 
      create table want as 
       select distinct *, stdt as STDFT format date9., stdt as ENDTFT format date9.
       from dates
      where cond=1 and date between "stdft."d and "endtft."d; 
quit;

What it says. The string

stdft.

is not a valid date in DATE9. format (which is needed for a date literal).

Your variables STDT and ENDT are already valid SAS dates. You don't need to put quotes around them and add D as in "stdft."d. You can just use STDT and ENDT without modification.

proc sql; 
      create table want as 
       select distinct *
       from dates
      where cond=1 and date >= stdt and date <= endt; 
quit;
