I tried the following code and was very suprised this didn't work the way I had expected it to. Is my expectation correct or the way that it implements it correct? select * from a left join ( b join c on b.f1=c.f1 join d on d.f2=c.f2 join e on e.f3=d.f3) on a.f4=b.f4 I would like it to have all the rows from a left joined with the total inner join of the rest. It actually performs it as if I did not have parenthesis at all and had the inner join connected to the left outer join thereby excluding all rows that do not have a match from b to c Thank You Sim ---------------------------(end of broadcast)--------------------------- TIP 6: explain analyze is your friend
