Connection Problem

Hello,

I am having a problem connecting to postgresql using Access and ODBCDirect. I am not sure that the problem is a odbc related problem, but I figured that I would ask and see if I could get a answer. I am using Access 2000, PostreSQL 7.1.2 and pgsql-ODBC V 7.01.00.09. When using any other method of connection (linked tables, pass-through query's) all seems to work great. But when I try to use ODBCDirect I get a Type mismatch error from Access. Here is the connection code.

Private Sub cmdLogon_Click()

Dim FSEInfo As Workspace
Dim cnn As Connection

Set FSEInfo = CreateWorkspace("FSE_Info_ws", txtUser, txtPassword, dbUseODBC)

Set cnn = FSEInfo.OpenConnection("FSE_Info_cnn", dbDriverCompleteRequired, False, "ODBC;DSN=FSE Info;")

cnn.Close

Exit Sub

End Sub

The txtUser and txtPassword is supplyed by the user through a form. Also here is the log output from the linux box running PostgreSQL.

2002-01-23 10:06:33 DEBUG: connection: host=192.168.1.10 user=jtwatson database=fseinfo

2002-01-23 10:06:33 DEBUG: query: select version()

It looks to me like the connection was excepted and successfull, but I get a Type mismatch error # 13. Can anyone help me out here. Any feedback would be appreciated.

Hi

I was just wondering if ADO with the OLE DB provider for ODBC not a better
choice is to connect to Postgresql? ODBCDirect is really just RDO ( Remote
Data Objects ) using DAO object names. Do you experience better performance
with ODBCDirect than ADO?

Kind Regards
Gerrit

Well to be honest, I don't know. I need to be able to start a transation,
make query's, and then based on the results, I need to decide if I can make
the changes to the database, then commit or rollback. This was not working
with passthrough queiryes, but most likley I just don't know enouph, and
was doing it wrong. So I am trying ODBCDirect. Also I want my database to
be client independent as much as possible, so if I can bypass Jet, I would
like to.

Hello,

Has anyone used MS ODBCDirect with pgsql-ODBC V 7.01.00.09 and PostreSQL 7.1.2 successfully? I am wondering if there may be a conflict between the odbc driver and ODBCDirect?? I can make linked tables, or pass-through query's work just fine, but not ODBCDirect. I get a Type mismatch error. So if anyone has make this work, please let me know so that I can narrow things down a little. Thanks for any help!

Can you send me the Mylog debug output ?
You can turn on the Mylog option using ODBC Datasource
administraotr.
