how to get result with row name with join(2 cols same name)?

Hi, I just ran a query something like this

select * from tab1, tab2 where tab1.f1 = tab2.f1 and tab1.f2 = X;

here the output has 2 f1's

I havent written the code to see what happens, but was wondering what will
happen if we do

row["f1"]?

Thanks
