Hi All,

I am running Teradata queries from MS Access using a ADODB.Connection. The
queries run directly unsing Teradata in about 3 Min. I can't keep the ADODB
connection from timing out before three minutes. The error message is:

"[NCR][ODBC Teradata Driver] Query Timeout Expired"

I guess that I don't understand the ODBC reference on a ADODB.Connection.

Anyway:

I have other quicker queries that run fine.

How do I keep from timing out?

Thanks

Ross

So you're doing this in VBA code rather than via a passthru query, correct?

There is an ole db provider for ODBC databases ... you must be using an ODBC
dsn ... ehich isn't really relevant.

You can increase the timeout (or set it to 0 so it's unlimited) by using the
Connection's CommandTimeout property (or the Command object's corresponding
property if you are using an explicit Command object).

Bob,

You are my hero, I have been working on this for days!

'************************
Public Sub Connect_Teradata()
'************************
Dim cmd As ADODB.Command
Dim prmPeriod As ADODB.Parameter
Dim stProcName As String
Set cnTD = New ADODB.Connection
cnTD.ConnectionString = ""
Dim myString As String
Dim SQL As String


With cnTD

(From Bob)
cnTD.CommandTimeout = 0

cnTD.Open "PROVIDER=MSDASQL;" & _
"DRIVER={Teradata};" & _
"DBCName=tdwpprod;" & _
"Database=data_mining_development;" & _
"Uid=YYYYYY;" & _
"Pwd=XXXXXXXXXXXX"
End With
