How to merge two data sets in this case

[SeanZ]

Hi,

I have a seemingly easy question. I would like to know if there is any easy way to do it.

There are two datasets A and B, both include a variable stock id (ID). A is a very comprehensive one that has many more ids than B. Now I want to merge two together to get any IDs in A that are not in B. How to do it? Can I do it in proc sql?

Thanks.

Yes you can do it in proc sql. Use a left join.
