Обсуждение: ForwardOnly ?
Hello, I'm using some Control and Visualization tool ControlWeb for my aplication and saving information into the Postgres database through the ODBC driver. SQL queries works fine, but when I was to move through the open set of records using the procedures of the Control Web a did get following message : The fetch type for PGAPI_ExtendedFetch isn't allowed with ForwardOnly cursor is there any help about it ? thanks a lot Petr -- Odchozi zprava neobsahuje viry.

Do you have set forward cursors only in ODBC configuration ? I can use it with success, but I don't know about ControlWeb.

I din't set this option forward cursors only and I even can't find it to check the state of it. I'm using ODBC driver for windows and I looked to the system registry to the ODBC.INI section and there was nothing simillar. Is somewhere a guide for this detailed ODBC driver configuration ? thanks Petr >>Hello, >> >> I'm using some Control and Visualization tool ControlWeb for my >>aplication and saving information into the Postgres database through the >>ODBC driver. >>SQL queries works fine, but when I was to move through the open set of >>records using the procedures of the Control Web >>a did get following message : >> The fetch type for PGAPI_ExtendedFetch isn't allowed with ForwardOnly >>cursor >> >>is there any help about it ? > > > Do you have set forward cursors only in ODBC configuration ? > I can use it with success, but I don't know about ControlWeb. > > Lothar > thanks a lot >> >>Petr >> >> >>-- >>Odchozi zprava neobsahuje viry. >>Zkontrolovano Antivirovym systemem AVG. >>Verze: 7.0.308 / Virova baze: 266.10.2 - datum vydani: 21.4.2005 >> >> >>---------------------------(end of broadcast)--------------------------- >>TIP 4: Don't 'kill -9' the postmaster >> > > > > -- > Lothar Behrens www.lollisoft.de > Rosmarinstr 3 My public project: > 40235 Düsseldorf http://sourceforge.net/projects/lbdmf > > > > > ---------------------------(end of broadcast)--------------------------- > TIP 2: you can get off all lists at once with the unregister command > (send "unregister YourEmailAddressHere" to majordomo@postgresql.org) > > -- Odchozí zpráva neobsahuje viry.

I'm using ODBC driver for My understanding is that, if you want an updateable cursor, it has to be forward only. This is a limitation of the PostgreSQL ODBC driver. I believe that the "updatable cursors" driver setting refers to this. But I'm only working from memory here; I could not find a reference to this when I looked.

Someone > else please correct me as necessary. I use updateable cursors also when moving back. I do not remember, if it not works, when I move a row back after editing a row. But I must say, that there will be a problem with the 8.x ODBC driver. Even reinstalling the old 7.3.200 version it didn't resolved it. This is because the install process may be brocken. I have removed the 8.x driver by hand, before reinstallation of 7.3.200. The code for my ODBC abstraction classes are public. All can try it. See the link below. Lothar
I've tried both.
to switch off the updateable cursors
and to uninstall ODBC driver and install 7.3.2.
but still the same problem.
I've looked into the psqlodbc_xxxx.log and found this message :
