Hi there! I don't know if my english is good enaugh to tell you what I want.
I have 3 Tables, lets tell them A, B and C. The relations: An A kann have some B's and a B can have some C's. But the main Select will be: and_(A.c.a_id==B.c.a_id, B.c.b_id==C.c.b_id, C.c.c_id=some_integer) So now there are two joins. As you see, we have two joins. We would have only one by doing A B C and a R table, where R has all three ID's: R.c.a_id R.c.b_id R.c.c_id A relation table... and_(A.c.a_id==R.c.a_id, C.c.c_id==some_integer) would be enaught. But how can I save data this way with a mapper? Martin ------------------------------------------------------------------------- Take Surveys. Earn Cash.
