Hi!
I have a table witch saves e-mail accounts and I want to give the
user the opinion to select a favourite account, so I've created a
boolean column and I want to secure that only one record could have
the value=true. I would like to realize this with a trigger on the
IB, but my SQL-knowlegde is to bad.
