i know this is fairly similar to other posts but i am just missing something about getting this to work right. so i have two tables, a and b with fields that match, 1, 2, 3, 4. so i need to get a field in a to Y on an inner join to table b. i know sql really well but am new to sas and i am using eg.
so, if fields 1, 2, 3, and 4 match between the two tables it needs to set a.z='Y'...
i think i solved my own problem. here is the code i am using...
proc sql;
update a
set a.z='Y'
where exists
(select * from b
where a.1=b.1 and a.2=b.2 and a.3=b.3
and a.4=b.4);
i havent checked it but i believe this works well and gets what i need it to.
thanks...
