I have a table (Firebird) with two fields (login and logout) both
currently defined as DateTime fields. For various reasons I now need
to split each of these fields into 2 separate fields (one containing
the date portion and the other the time). Under MySQL I could do a
simple update query using functions to separate out the two elements
of the existing field. How do I achieve this under Firebird?

I am looking for something like:

update table1 set logindate=date(login), loginTime=time(login) ...

I don't really want to get ito writing UDFs as I don't have the time
or the knowledge.

Thanks
