Maybe you're right, and it'll be in future Firebird distributions. But it's still illogical. How can I update FROM anything? I can only update somtehing. And if I use Inner join, which table will be updated? I think it's much more logical to update something, where I can't find appropriate records in another table.

I think it's a pitty that FireBird (such an excelent DB Server)
hasn't YET this feature, because it's much more flexible to do update
and delete with INNER JOINS than the way to do the same with FireBird.
I could bet it'll have in the future ...
