option to reject existing duplicate rows but also allow non-duplicate rows to be inserted into table Topic by Jaycob 19 Jun 2013

Greeting All,
Just wondering if there's any option in TD allow user to insert partially only non-deplicate rows after creating a unique primary table like the undo_policy=none option in SAS. In this way, the process will reject to insert all existing duplicate rows but also allow non-duplicate rows to be inserted into table. Thanks in advance for any response.

Data Warehouse Testing Topic by RCC13 18 Jul 2007

I work in a Data Warehouse as a Quality Control Analyst. Development uses Abinitio as the ETL tool and we use SQL for writing our test scripts. I am trying to find out how other shops test their existing Data Warehouse maintenance projects. We use the functional and technical specifications to create our Test Strategy, Test Plans and Test Cases. We use a subset of production data for our test bed. We test all of the transformation rules stated in the specifications (some have very complex logic), creating ‘seeded’ test data to meet the criteria of the transformation rule if the data does not already exist. My Questions: How are other shops meeting the need to test all the transformation rules? Are other shops seeding data or only using what exists in production? If all transformation rules are not being tested is there a risk factor associated with the untested rules? In your environment does the Developer run the ETL graphs for loading test target tables or does your Testers run the graphs? Thanks.

MS access link to Teradata subset of views that is granted from a role Topic by Ron Fleck 29 May 2009

We are using MS Access as a front end to Teradata. We are trying to move to granting ROLES to users so that they can see only a certain number of views within the DB. But when we specify that DB as the default in the ODBC default database, we get error 3524 - The user does not have any access to database xxxIf we specify a Default DB in the ODBC connection wherein the user has access to ALL the views within that DB (either via ROLE or profile access), then MS Access connects and shows us all those views.Is there a way to have an MS Access link show the user ONLY that subset of views based on a role that is granted to just a few views in the Teradata database?Using ODBC driver 3.06.00.06

TDM vs Other Load Utilities Topic by Jigar 12 Sep 2011 tdm

Hi ,

 

We have a project where we FastExport data from one Teradata Server and Mload/Fastload it to another Teradata Server.However I recently found out we also have TDM available in our project.

I was wondering whether it is worth to change existing Fexp/FastLoad scripts to TDM or would the performance be nearly same in both the case.

Raise Error and Return value with in a stored procedure Topic by Abhisek 03 Dec 2009

Hi,I am trying to convert Stored procedure from Sybase to Teradata. Sybase has the option to raise error as well as return 0 or 1 for (success or failure).The scenario is as follows,1) SP1 2) SP2Call of SP2 depends on the return value generated by SP1 ,for eg, create procedure SP1(@z char(2))as if (char_length(@z," ") <> 2) begin raiserror 20000 return 1 end return 0exec @retcode=SP1 @zIF @retcode = 0 exec @retcode=SP2 @zELSE return 1So here in this case, if the return value is 1, then the other stored procedure shall not execute and if its 0 then SP2 would get executed. This functionality is supported by Sybase.I tried implementing the same functionality in Teradata using OUT parameter.However when the stored procedure SP1 executes successfully the out parameters set to 0, but if SP1 fails with error the OUT parameter doesn't return any value.Please help in this regard.

Teradata dump - Prod to dev Topic by kondalmrao 25 Nov 2008

Hi All,We are trying to setup a teradata server for our dev environment and we would like to replicate the production environment but with only sample data(limited no of records in each table). Needless to say, our dev env has less space compared to teh production.What is the easiest/Industry standard way of doing this? Also, is there any way we can parameterize the no of records from tables in particular database (Ideally, we would like to copy all the data from the process control/metadata tables but only samples from the real data tables)I have heard of the arcmain utility but i am not sure if we can get samples of data from each table in the arcmain dump. Appreciate any help on this!Thanks.
