Hi Andrey,

Thank you for your interest in MySQL software.
I was able to repeat the problem you reported with Connector/ODBC version 5.2.5, but the recently released version 5.2.6 worked well for me.
Do you think you could give it a try?
The versin 5.2.6 is now available for downloading from the following page:

Please let me know about the results.
Thanks.
