Okay, my SQL was wrong. I'll amend it when I am back.
Thanks.

In this case it will not be a problem, because I will not have this
amount of records, but it is good to know.
I am not a database expert, but I thought that with hash-tables you
should not have this problem. That is not the case?

The reason to use them is that it is easier to merge databases. (The
'same' application will run on one or more pc's and one or more
mobiles. In this way the data can be merged. Or is there a better way
for that?)

The other question I could better repost in another thread. ;-}
