Hi, Dave,
I already tried all the three drivers under the
8.0/jdbc directry and get the same error message. Can
you provide a URL of the documentation in regarding of
the difference among the three drivers.
I will change the server character configuration to
overcome this problem. I had a typo in my email of the
IP address.
Thanks a lot for your promptly helps.
