Re: PostgreSQL: Autocommit through windows odbc driver doesnt work!!!

Hi Adrian,

Sorry for getting back to you late. I tried with psqlodbc version, 09.05.0100 but the issue is still seen?
Let me know what next step I can follow to root cause this? Any tracing you would suggest?

Thanks,
Sekhar

So have you tried the latest psqlodbc version, 09.05.0100 ?
