Hi at all, is my first question here, so be patient ^^

I'll go directly to problem, I have two table Customer (idCustomer, ecc.. ecc..) Comment (idCustomer, idComment, ecc.. ecc..)

obviosly the two table are joined togheter, for example

SELECT * FROM Comment AS co
  JOIN Customer AS cu ON cu.idCustomer = co.idCustomer

With this I select all comment from that table associated with is Customer, but now I wanna limit the number of Comment by 2 max Comment per Customer.

The first thing I see is to use 'GROUP BY cu.idCustomer' but it limit only 1 Comment per Customer, but I wanna 2 Comment per Customer..

how now to proceed?
