How do you connect to a DB View with OData in Visual Studio?
Does anyone know how to connect to a DB View with OData service in Visual Studio? I can connect to DB tables, as in the tutorial: Creating an OData service using .NET Data Provider for Teradata (http://developer.teradata.com/connectivity/articles/creating-an-odata-service-using-net-data-provider-for-teradata). But I cannot select a particular View.
I found article "Specifying Views In the Entity Data Model (EDM) Wizard"http://developer.teradata.com/blog/dsakai/2011/04/specifying-views-in-the-entity-data-model-edm-wizard, but it's from 2011 and is very cumbersome and frankly out of my expertise. I would think there is an easier way by now. Does anyone know or have been able to connect to a view relatively easily?
I am using both VS2010, Win7, .NET Data Provider for Teradata 14.11 release. I also have VS2012, but that does not even list Teradata as an installed product (topic of another post).

What is the TDPID and how to do remote connections
Hi All,
I'm a newbie so please forgive my silly questions. I really appreciate any assistance.
1. What is the TDPID and can it be changed for different interfaces such as one for the 1GB interface and another for the 10GB interface on a Teradata server?
2. What is the best practice or recommended method to have remote user connections to access Teradata database such that the connections are load balanced across all nodes with failover to the HSN when it comes online due to a node failure? We are trying to setup COPs aliases for CLI and ODBC connections and need some guidance. We are setting up the below (contrived example):
IP -> ANAME -> CNAME (<TDPID>cop<n>
10.30.250.1 -> tdprd01 -> prd1cop1
10.30.250.2 -> tdprd02 -> prd1cop2
10.30.250.3 -> tdprd03 -> prd1cop3
Thanks for your kind assistance.

Unable to connect to teradata
Hi All,
I am new to Teradata. I have knowledge on Oracle. Recently I installed Teradata 13 version on my lap through VM. I completely installed Teradata tools and utilities. Now I am not able to connect to Teradata through SQL Assistant. While I tried to connect it's showing Error. Below the error log:

Teradata] [100038] is there a timeout parameter?
Extract Beginning for BigComp Extract Begin date is: 2014/03/01 End date is: 2014/03/31 Exception on Teradata Open for: bigdw.bigcompany.com myuid LDAP Message is: Teradata.Client.Provider.TdException (0x80004005): [.NET Data Provider for Teradata] [100038] Command did not complete within the time specified (timeout).

Hi,
I wanted to add some information about this and ask a question. Our group decided to do a large number (~20) of extracts using dot.net to create an ascii file and then read it in with ms sql bulk copy (as opposed to use ssis or datastage). Most of these extracts worked fine but with one of them I got the error message I show above. Which brings me to one piece of information I am offering. The query you are using can cause a 1000038 error message even though the infrastructure you are connecting with is correct. In my mind the query that caused the failure, fails for subtle reasons. This query is large (returns 40 million rows) but I have other 40 million row queries that work fine, so it's not just the size of the return set. I think dot.net wants a few rows back within some timeout limit or it thinks nothing is coming back and this query doesn't give anything back within the timeout limit. So cb.ConnectionTimeout increases the amount of time dot.net has to connect to teradata with uid/pw. Is there a parameter that can increase the time dot.net waits before rows come back from a query? Environment is Teradata Client 14.x, c#, Visual Studio 2010. ... Flash

setSavePoint exception
Hi Team,
I am getting following exception while calling setSavePoint of Connection interface.
SavePoint currentSavepoint = connection.setSavepoint("BatchSavePoint");

Also, I couldn't see the mention of this method at this link:

Can anyone suggest whether savepoints are supported by Teradata JDBC driver or not?

Windows .Net (non-ODBC) connection to Teradata using LDAP authentication
I am trying to use the Teradata .Net connector (v. 14.11.0.1) to establish a connection between my c# Windows application and a Teradata DBMS. I am not using the ODBC connector so there is no DSN associated with the connection.
We are testing this on a client system as we do not have a Teradata system in-house that uses LDAP for authentication. We cannot establish a connection using LDAP. However, the client is using a different application that connects through a Teradata ODBC-based connection with LDAP as the authentication mechanism.
I see some posts to this form that say this should just require a properly crafted connection string, e.g., http://forums.teradata.com/forum/connectivity/net-connection-string-with-ldap. I've tried this and whatever variation seemed feasible without success. (String is similar to: Authentication Mechanism=LDAP;User Id=dbc;Data Source=192.168.3.56;Password=dbc)
Other docs indicate that a custom assembly has to be created to provide AD attributes for the connector, e.g., http://www.info.teradata.com/HTMLPubs/DB_TTU_14_00/index.html#page/Database_Management/B035_1100_111A/Configure_LDAP_Mech_Properties.105.28.html. Under the debugger, I can see that a test assembly so created was indeed being loaded at runtime by the connector. This direction leads to two problems: 1) having the user provide the AD attributes, and 2) dynamically creating the assembly on our client's installations because we're not going to separately create this assemblies for each of our customers.
My question is, from your experience, what is a reliable way to use LDAP in this systems? Am I missing something in trying to craft a simple connection string? The second method seems to provide AD info that would be necessary to connect via LDAP. However, it will take a bit of code to allow the user to enter their AD attributes and then generate an assembly on-the-fly. I'm almost at the point where I'm going to back out to the ODBC-based driver in the hopes that the ODBC driver setup will handle the LDAP issues.

JDBC FastLoadCSV Connection; multi character field separator??
Is this possible? I see in the FastLoadCSV docs that you can specify other field separators besides comma.
I'm using the old CLI version of fastload all the time now, and a lot of my data has unfiltered user input, so one of my favorite features is to be able to use something like |~| or ^^^ as a field separator. If I can't do this via JDBC, I'll have to change a lot of my load processes, and watch out for users that put ascii pictures in their description fields.

TDOLE DB Driver 14.1 - A dynamic link library (DLL) initialization routine failed
Hi,
I am getting an error message “A dynamic link library (DLL) initialization routine failed.” when I try to access Teradata database from within my ETL tool, SQL Server Integration Services (SSIS) 2008 package.
A bit more detail on the error description:
A dynamic link library (DLL) initialization routine failed.". ..Error: 2014-05-19 06:00:02.77 Code: 0xC020801C Source: OLE DB Source [1] Description: SSIS Error Code DTS_E_CANNOTACQUIRECONNECTIONFROMCONNECTIONMANAGER. The AcquireConnection method call to the connection manager "Source_Teradata" failed with error code 0xC0202009
This error started occurring ever since I uninstalled the v12.0 of Teradata drivers and installed v14.0 of Teradata Drivers & Utilities. Prior to this uninstallation, the SSIS packages were working fine connecting to Teradata database.
Some of the environment details are as below:
OS: Windows Server 2008 R2 Enterprise
Teradata Drivers: v14.10 32-bit
Teradata Utilities: v14.10 32-bit(FastExport/FastLoad/BTEQ/Multiload)
Note: Exactly the same installation in Staging environment, however, is working fine.
Any thoughts on this issue please.

I'm not sure what the "Generic Download License" really means. Is it possible to use the downloaded software for production if we have valid license for Teradata RDBMS?
e.g. use downloaded ODBC driver 14.x while we only have license for TTU 13.x.
(a) Subject to your compliance with all of the terms and conditions of this Agreement and only during the term of this Agreement, Teradata grants you a nonexclusive, nontransferable, paid up license to install and use the Software on your computer workstation (the configuration of which meets the requirements for installing the Software) solely for purposes of

Will exisiting .Net connectivity be affected by upgrade from 13 to 14.10?
Hi, I currently have a connection from SQLServer 2008R2 integration services to Teradata v13. The version of Teradata is due to be upgraded to v14.10 soon, and I am trying to confirm if my connection from SQL Server will be affected or not.
The .Net drivers are from the Teradata Tools and Utilities - Base 14.10.03, so I am assuming that this will continue to work, but I am hoping to be able to confirm this.
Any advice or pointers greatly appreciated!
