I am trying to determine if I can combine a keep and a where in a set statement.
data sf;
set screen (where=(sf_flag='Y') keep = ( cno patno sf_flag) );
run;
Yes, that's perfectly possible. I'd just change the order of the two dataset options, as SAS executes the keep first and the where later.
In a dataset option, you can only apply the where to variables that are kept, as apposed to SQL, where you can set a where condition with variables not included in the select.
If you also use a rename= option, the order should be
keep=
rename=
where=
as that is the order in which SAS executes the option, so that the code as written represents the logical order.
