Question

Does any one know how to insert only “new” row to the existing table with in SAS PROC SQL ?

proc sql;
 create table class as 
 select * 
 from sashelp.class 
 where sex = 'F'; 
quit;

proc sql;  
 create table classm as 
 select * 
 from sashelp.class 
 where sex = 'M' or Name = 'Alice';
quit;

proc sql;
 insert into class 
 select * 
 from classm ;
quit;

The insert statement does not allow me to use where statement to insert only 10 new row from classm ( without Alice )

Is there a way to go around this ? Because I’m working with big data I would like to do this with in proc sql , or data step is fine.

Thanks

This worked for me…

proc sql;
create table class as 
select * 
from sashelp.class 
where sex = 'F'; 
quit;

proc sql;  
create table classm as 
select * 
from sashelp.class 
where sex = 'M' or Name = 'Alice';
quit;

proc sql;
insert into class 
select * 
from classm 
where name^="John";
quit;
