can i write the below two steps in one step?

proc sql;
create table tempexclusion as
select b.*
from acc as a
    right join prep as b
          on a.tlnbr = b.phone
    where a.tlnbr is not null;
quit;

proc sql UNDO_POLICY=NONE;
create table prep as
select b.*
from acc as a
    right join prep as b
          on a.tlnbr = b.phone
    where a.tlnbr is null;
quit;

I may be somewhat blind, but what is the difference between the two steps (a part from different target table names)???

If the question is if you can create multiple table in one SQL statement, so, no, not in SAS.

If you mean to call proc SQL only once, you can use the reset statement :

proc sql;
create table tempexclusion as
select b.*
from acc as a
    right join prep as b
          on a.tlnbr = b.phone
    where a.tlnbr is not null;
RESET UNDO_POLICY=NONE;
create table prep as
select b.*
from acc as a
    right join prep as b
          on a.tlnbr = b.phone
    where a.tlnbr is null;
quit;

Oh, no I see, not is a small word...

Well, I guess you just need to remove the where clause. Or what is you want?

is the reset option better in terms of efficiency or run time? or am i just reducing few lines of code?

thanks for the reply

There must be a small efficiency gain but I doubt you will ever notice the difference. - PG
