You should filter the buying dataset using the buyingid variable prior to the inner join. Take a look at the "where" clause for sql.

--------------------------
The hash OUTPUT method will overwrite a SAS data set, but not append. That can be costly. Consider voting for Add a HASH object method which would append a hash object to an existing SAS data set

Would enabling PROC SORT to simultaneously output multiple datasets be useful? Then vote for
Allow PROC SORT to output multiple datasets

--------------------------

Your code seems incorrect.

You would first filter your table 2 based on purchase and then get the corresponding names from table 1.

Given your question and data, I'm not sure how you'd filter as there isn't an item code that I can see.

Is there a reason you're not doing this entirely within SQL?
