I tried undac 1.2 Bate for D2009.
my table have chinese field name.
when select form table. it works fine.
but on update , it show erroes!
1.2 Bate can't use chinese fields!
Probably this is the same problem as you described in the topic varchar2 fields numbers can't more than 2. Please specify whether you get an error with Oracle provider, and whether the error message is "update error, found 0 records".
