Summary: Autocommit and Cancel

Initial Comment:
Our application in one thread issued long time SELECT, another thread cancelled this statement. After that first thread tried to issue next SELECT and got error message because current transaction is aborted with error. As I saw in postgresql server logs there was no ROLLBACK statement issued by driver after cancellation.

We're using autocommit mode. Mylog file is attached.
Server version is 7.4.6, psqlodbc version is 08.01.0101.
Also, we use unixODBC 2.2.8 with option "Threading=0" in odbcinst.ini.

Thank you.

I've tried this version from development snapshot.

* 1000457. Cancelling statement from another thread is working
fine. There was normal "ROLLBACK" in thread that called target
statement.

Bug is fixed.

Message:
Sorry for missing mylog, I'll try to resend it into pgsql-odbc, because I can't attach file into existence issue.
Also, I couldn't try your driver, because it's for Windows, but I'm using Linux and unixODBC.

Thank you.

I try to fix this problem. Please try one of attached drivers. Send me feedback throught pgsql-odbc mailing list with attached mylog and with yours odbc.ini settings for used datasource (I think you have to use usedeclarefetch option).

I see no mylog attached (as you wrote you attach one).

Message:
There is problem that exec is blocking and cancel is for non-blocking operations.
I'll fix it as soon as possible.
