Re: ODBC Connection returns no Data

Hello Bob, thank you for the quick and deep answer.
AR System is the Remedy Action Request System, a Ticket-

OK, so it's a proprietary database for which an ODBC driver is supplied

It's right, that recordsets open even without data, but the
SQL-Commandtext should return data.

?
Oh! I think you mean that the statement you've supplied for the CommandText
should return data ...

If I paste the Commandtext in the MS Query SQL Editor via Excel, the
String returns data. But in the VBA-Code, rs.EOF returns true.
But I can enumerate the recordset-fields
an if I change a fieldname
in the command text, there is an error, that ADO can't find the field.


We had an update of the AR System Frontend and the ODBC Driver version
changed. Before the update, the same code worked. OK, I should contact
the support at first, but I don't understand, why ADO does'nt work.

MS Query works directly against the ODBC driver.
ADO adds an extra layer: the OLEDB Provider for ODBC databases. I suspect
your new ODBC driver is not interfacing well with the new driver version.
You should definitely contact support. They will likely need a better repro
script than the one you provided below (which is OK since it's unlikely any
of us have a copy of this AR system to enable us to attempt to reproduce the
problem)

And Yes, I think, Excel uses the same driver. That is, what I don't
understand.
I tried to change the CursorType, the CursorLocation, I tried to get
the Recordset via connection.Execute, I tried the Connection string via
a ODBC DSN name, I tried to specify only one fieldname without
"WHERE"-Clause, I tried different parameters in the connection
string, I tried different
parameters in the "Open"-methods
I have no idea anymore.
Here some Code:

Dim conConn As New ADODB.Connection,

Nothing to do with your problem, but this is bad practice. You should remove
the "New" keyword from these Dim statements and use Set to initialize these
variables, i.e.,

Dim conConn As ADODB.Connection
Set conConn = New ADODB.Connection
Dim rsODBC As ADODB.Recordset
Set rsODBC = New ADODB.Recordset
