Hi,
I got excatly the same question few days ago...so I can reply...
But unfortunately it's not possible, with hibernate you can just see the prepared statement and value for each parameter...then reconstruct your query...but it's quite complicated for nothing...
Someone, indicates the following tool...I haven't tried yet because I have other problem but If you try please let's your comment on it here....if you have any problem I can install it and try with you...
