How did Teradata get its name? Does mistletoe grow in parse trees? If there are “virtual AMPs” are there “virtual Watts” as well?

Hi,
 
In my server I am running TD Express for VMware, version TD14.10. I have created several users and have no relevant data there (its a sort of sandbox for some users).
I would like to create all the users and keep the same passwords. I am guessing that this could be done exporting and loading some tables into TD15?

We are using Teradata Parallel transporter (TPT) loaders as both source and target connection.

Hi,
When I am trying to export data from Hadoop Hive to Teradata I am getting Datatype mismatch exception, especially for Date and Decimal format.
Just for testing, I tried to export the same Hive table to TD, that was imported from TD into Hive with same schema. But it didn't work.

I've been trying to download the TDE 14.00.03.02 for VMware (4GB). Its not downloading. Are they unavailable at present. Are the VMware versions of Teradata Express for 64 bit the only option? They seem to be problem prone.

Hi,
I am not sure if this is the right category of the current issues we are facing right now. Unity Director had been implemented in our client together with the Teradata database implementation. I am not sure if this is a verified bug but below are the current scenario we are facing.

Hi Experts,
As per one of the requirement , we are making one column as CHARACTER SET UNICODE CASESPECIFIC.
But as we know that in Unicode too we have two types of character sets UTF-8 & UTF-16.
Can we know some how which one  (UTF_8 or UTF-16?) would be created after making the column as UNICODE?
Thanks in advance!

Hi
In a script, at Session level the transaction isolation is set to RU (Read Uncommitted or ACCESS).
At table level I am overriding to READ lock for Table1 in a SQL select.
 
Now if there is already an INSERT / MERGE / UPDATE operation going on Table1 then it will be on WRITE lock. So the SQL with READ lock will wait.

Hi Masters,

 

This is a Hadoop/Teradata scenario. I'm looking for advise for a data migration from Hadoop to Teradata. The source data is supposed to be coming in form of delimited flat files. What are my best options for migrating data with best performance.

 

Greetings,
I'm generally more of a forum lurker, but every once in a while I get something working that doesn't readily work out of the box the way you'd expect and feel that its worth posting about to ease the path of others (and maybe leave a trail for Google to scan so I don't have to remember where I left my notes!)

We have several queries that sometimes get stuck in response mode. Is there a way to real time see what the queryid is of a query that is currently in response mode? Using the following:
 
SEL a.*,
    b.sqlrowno,
    b.sqltextinfo
FROM dbc.qrylog a
     LEFT OUTER JOIN dbc.qrylogsql b

ALTER TABLE XXX
 ADD CONSTRAINT R_374 FOREIGN KEY (QuarterPeriodNum) REFERENCES WITH NO CHECK OPTION YYY (QuarterPeriodNum)
[Teradata][ODBC Teradata Driver][Teradata Database] Incorrect referential constraint definition.
Execution Failed!
ALTER TABLE Failed. 3976:  Incorrect referential constraint definition.

I belive we cannnot load a CLOB column thorugh utility...
Work around -->

Recently we were forced to build out a new instance of Teradata V12.  During the "configuration" phase of the install.  I get to the step "Run Config and Reconfig".  The Config steps runs without issue however when it goes to run Reconfig it throws an error.
 
If anyone has run into this and knows the answer please let me know.
 

 
Is it possible to combine two heterogenous sources and load into one particular target. If so How using TPT?
Ex: I'm combining data from Oracle and DB2 and loading into one Teradata Table.
