Обсуждение: 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.

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.

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

If I remove the above line(Connection), the following
seems to work though I don't understand the reason.

If it were VB I'd say in a flash that ADO is referenced in the project
before RDO/DAO and conn was defaulting to ADODB.Connection. Is this possible
in Access?

Oh I see.
Joseph, please change the line like
    Dim conn As DAO.Connection
and try.

Hiroshi Inoue

Thanks so much for all the help

I moved the DAO 3.6 up the reference list and this fixed the problem and it
works.

Thanks so much.

Joseph

I don't see anything funny in any of the logs myself.  In the PostgreSQL
log, it shows that the connection was successfull, and some default quiries
are executed and all looks good.  Likewise in the logges generated by the
ODBC driver, all look okay.  It seems to me that what ever is returned to
VB from the ODBC driver is not of the right data type.

Here is my VB code:

Private Sub Command5_Click()

    Dim FSEInfo As Workspace
    Dim conn As Connection
    Dim connstring As String

    connstring = "ODBC;DSN=FSE Info;"

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

    Set conn = FSEInfo.OpenConnection("FSE_Info_cnn",
dbDriverCompleteRequired, False, connstring)

    conn.Close

    FSEInfo.Close

End Sub

The error occurs on the "Set Conn" line, and reads:


    Run-time error '13':

    "type mismatch"

and here is the log from PostgreSQL,

2002-01-26 06:25:39 DEBUG:  connection: host=192.168.1.10 user=jtwatson
database=fseinfo
2002-01-26 06:25:39 DEBUG:  query: set DateStyle to 'ISO'
2002-01-26 06:25:39 DEBUG:  ProcessUtility: set DateStyle to 'ISO'

2002-01-26 06:25:39 DEBUG:  ProcessUtility: set geqo to 'OFF'

2002-01-26 06:25:39 DEBUG:  query: select oid from pg_type where
typname='lo'
2002-01-26 06:25:39 DEBUG:  query: select version()

It lookes like the connection was successful and there was 5 successfull
queries made.  But I get a error dialog popup in access saying type mismatch
error.  It seems that the data returned to VB by the ODBC driver is being
rejected by the connection data type???

I attached a Access 2000 database that will reproduce this problem.  Just
edit the DSN to match one on your machine.

Thanks for the help thus far.
