Hello all. I have a question about merges. What I usually do is:

data new;
merge data_one data_two;
by key_one key_two;

My first question is: If both datasets have the same variable names, which
one will prevail?

Also, can I do a merge with set statements? Eg:

data new;
        set data_one key=key_one/key_two;
        set data_two key=key_one/key_two;
        if _iroc_ = 1;

Will this work the same as the normal merge statement?'
Thanks.
