I need to select everything from table A where the data is from previous day.
Table A has "Date_Key" which is numeric
Example: 20110805
How can i subtract 20110805 - 1 in Proc SQL to get 20110804 data ?
Thanks
Depends upon whether that numeric field contains a SAS date that is only appearing in that format, or the number 20,100,805
If it is already a SAS date, then you would only need Date_Key-1
If it really is the number 20,100,805 you could use something like:
data have;
input Date_Key;
cards;
20110804
;
proc sql;
select *
from have
having input(put(Date_Key,z8.),yymmdd8.)=today()-1
;
quit;
