如何在sas中使用proc sql，在另一个表中使用in语句

Question

proc sql;
   create table X as
   select a.date, a.exdate
   from optionm.opprcd as a
   where a.volume>0
     and a.secid in (secids);
quit;

I want to do something like the above. Create a table taking data when the variable secid has values that appear in a table called "secids". Since the values that I want are approximately 600 I cannot use in (100, 101, etc). I need to somehow extract these values from another table.

Any help would be much appreciated, since I am not an expert in SAS.

Answer 1

proc sql;
create table X 
as select 
a.date,
a.exdate
from optionm.opprcd as a
where a.volume>0
and a.secid in (select /*column*/secid from /*table*/secids)
;quit;

note - quit!

Answer 2

Try this:

proc sql;
    create table X as
    select a.date, a.exdate
    from optionm.opprcd as a,sec_tab b
    where a.secid=b.secids and a.volume>0;
quit;

NOTE: Basically, Join is faster than subquery.
