hello, thank a lot.
 
but when I use:
import kinterbasdb
kinterbasdb.init(type_conv=300)
self.con = kinterbasdb.connect(dsn=os.path.join(module_path(), folder, db), user=usr, password=psw)
self.cur = self.con.cursor()
select...
self.con.close()
 
I am getting ProgrammingError: Cannot initialize module more than once when I try to use it again. This happens when I use .init(type_conv) Why? Any workaround? thanks.

You need to call KInterbasDB.init(type_conv=300) and RTFM:
