Thread: psqlODBC and MS-Access
Hi people,
Many thanks to Justin Clift for pointing me to this list.
I am having a long running problem which i am hoping someone can help me with.
I have installed postgreSQL on a new gentoo install and managed to get it working correctly. I have also downloaded and installed the newest ODBC drivers i can find.
I have set-up the accounts, IP addresses and the like appropriatly but still cannot export from an access to a postgresql database. When i attempt the export command i get an error of:
"ODBC Call Failed
ERROR:Length of VARCHAR must be at least 1 (#7)."
When i attempt to export tables with no text in them (i.e. text, memo and hypertext) they export with no problems. Can anyone help me with this as i have spent a good three or four days looking for the solution.
Cheers,
Marc
Cheers,
Marc

Running the script outside of an MTS transaction works fine. It crashes inside.
I was hoping that PostgreSQL+ would address this... Any ideas?

Maybe MTS requires Distributed transaction support but
PostgreSQL(and of cource psqlodbc driver) doesn't support it.
I'm not sure if MTS provides the option to work with non-
distributed system.

Perhaps, but the MS Access ODBC Driver would run in an MTS transaction, even though there is no transaction support in access. I use ODBC like I drive my car. I put in the key, turn it, and it just works. What could I do to get under the hood and find out what this mysterious "Set" thing might require to function properly? I don't care to even have the PostgreSQL transaction auto-roll-back when the MTS Transaction fails. I need the transaction support for the larger operation of which the database transactions are a small part.
