Lookup As Inner Join ??

Hello all.....

I got a doubt whether we can use Lookup as an inner join.
If I have duplicate keys in lookup source....can I get the duplicate rows also into the destination.

Ex:
source:
c1 c2 c3
--- --- ---
1 a1 b1
2 a2 b2
3 a3 b3

lookup table:
c1 c4 c5
--- --- ---
1 c1 d1
2 c21 c22
2 c23 c24
3 c3 c3

noe the result should be:
c1 c2 c3 c4 c5
-- -- -- -- --
1 a1 b1 c1 d1
2 a2 b2 c21 c22
2 a2 b2 c23 c24
3 a3 b3 c3 c3

in msdn I read the look up will get the first match.....is it possible to get all matches??



Thank you
