While that makes sense, I suspect there is something else going on. I did a few more tests. For example, if I remove the INSERT but keep the exact same SELECT statement with the joins, it is fast again. So, it seems that it is quite slow when doing the insert's. I was thinking that perhaps the statement was not in a transaction, but I tried that too. ____________________________________________________________________________________ Do you Yahoo!?
