yes all or nothing...

if the procedures gets an error then I want to give the user a chance to correct the values that s/he entered the form by rollbacking the second not rollback all the data. Indeed I need nested transactions but firebird doesn't support it yet..

regards
burak..

Sounds like you're interested in a "all or nothing" thing, that is, all the
SQL statements must succeed or you want none of them to succeed. A single
transaction does just that, either commit or rollback..
If that's not what you're trying to do, please explain further.

I need the second Transaction becouse of data security.
I start a transaction then I run lots of procedures in an other transaction
if procedures works well then I commit trn2 then trn first.

I think you can do this by doing both in Transaction 1. Why do you need 2
transactions?
