When you implement an equi-join as a nested loops join, the right-hand side
always has a filter combining the variable set by the left-hand side and the
join column on the right-hand side.
You will need to do a full scan of the right-hand table every time, unless your
table is organized so

Hi Gabriel,
What you want indeed seems to be a nested loop join; there has been a
