I have 100GB SAS dataset on LINUX. Space allocated for the dataset after deleting 50 GB data from the dataset is still 100 GB. I'm not sure if this is related to SAS or LINUX.
The below code is performing the delete:
Proc SQL; Delete * from dataset where Column=value; Quit;
i have tried below Query also but again Size of dataset is still same .
QUERY :-
LIBNAME LIBNAME '';
Data LIBANME.DATASET NAME ;
MODIFY LIBANME.DATASET NAME;
IF condition then remove ;
Run ;
To reduce the physical dataset size, do this:
Data LIBANME.DATASET NAME ;
set LIBANME.DATASET NAME;
IF not (condition);
Run ;
