Dear all,
I have various proc sql programs that each contains a clause ' When date = '30Mar2017'D'.
How can I optimize the process by stating at the beginning the date and not changing the date within each proc sql?
Thank you.
Use a macro variable:
%let refdate=%sysfunc(inputn(30mar2017,date9.));
and later
when date = &refdate.
