hi,
i search a TPT syntax but i'm not sure if it's possible.
i have an input fixed file's. Two columns as a varchar(15) and a varchar(8) and the second column can contain 8 space caracter wich convert it as null value.
In the block SCHEMA or OPERATOR, is it possible to define the conversion or is it only possible to the APPLY statement with case when syntax ?
 
DEFINE SCHEMA FILE_xxx
(
aaa VARCHAR(15)
, bbb VARCHAR(8)
);
 
DEFINE OPERATOR FILE_xxx_READER
DESCRIPTION ''
TYPE DATACONNECTOR PRODUCER
SCHEMA FILE_xxx
ATTRIBUTES
(
    VARCHAR DirectoryPath = @DirectoryPath,
    VARCHAR FileName = @FileName,
    VARCHAR Format = 'Text',
    VARCHAR TrimColumns = 'Both',
);
 
Thanks lot for response

TDCH-TPT Interface--For loading into Hadoop

I need to ingest volume of data from Teradata to Hadoop using TPT.I saw in the TPT documentation that we can achieve this using TDCH-TPT interface.I would like to know the following about the process:

  1. Whether it follows the same process and extracts data block by block.
  2. Whether it utilizes all the nodes in the cluster while loading into Hadoop.
  3. In this case whether TPT needs to be installed in all the nodes in the hadoop cluster?
  4. For 1 single table ingestion and export to hadoop whether both the read(Teradata) and write(Hadoop) whether both the process are multithreaded while using TDCH-TPT interface.

In List Blues - How to make large In List Queries More Efficient

July 18, 2016, 1:36 pm
$

I work for a bit company with a lot of Business Objects users. One of our most popular universes points to a Teradata environment. This universe is by far our best BI resource. It has a ton of data and it delivers it to the users lightning fast. However, some of our users like to utilize a prompt that allows them to input a tremendous amount of data as an "in list" where clause.
While Teradata does a tremendous job on all other queries, it seems to choke on large "in list" queries. The amount of CPU usage for just a few of these queries is sometimes equivalent to hundreds of other queries. I've been told that this is because Teradata is not able to make use of parallel processing for these type of queries.
Our goal is to improve the efficiency of these searches with minimal impact on the users.
So, one possible solution is to create a global temp table in Teradata and fill that table with the prompt values from the user. The temp table would include pertanent joins, which should, theoretically, improve performance by allowing Teradata to make use of its parallel processing. Keep in mind that the majority of queries use the same object(column) as a search criteria and this object happens to be the unique key that is indexed, so this solution could work well.
The problem is that Business Objects does not really have a way to write data to a database. So one of our lines of thought is to use a Bteq script to load the objects into the global temp table.
Is it possible to create an if/then statement using BTEQ on the Teradata database that looks for a condition of something like:
If user = user X and Object X in list"Abc, ABd......" then insert into global temp table
Then query and deliver the results to the customer. Can this be done on the database or does it have to be done in Business Objects?

Hello Gurus
Is there a rule of thumb that one should follow for determining the number sessions that should be set for a load or fexp jobs?
Suppose if my system is a 4 node system with 40amps/node , what would be the best practice?

Hello Folks
I have a requirement to move 90 tables totalling up to 200 GB from one Teradata system to an another Teradata system.. While i know there are different options i plan to use TPT to move them..All the column data has to be moved..
TPT requires to define schema layout .. Is there a way to do without the schema layout? I dont want to do it manually .. Has any one developed a reusable script for moving data where the scipts reads 1 table moves the data then moves to 2 nd table and so on?

Float data type export using Fast Export

July 19, 2016, 9:32 am
$

Hello everyone,
 
I am trying to export a table with float data type using FastExport utility.As we know Teradata rounds-off any float values where number of digit is greater than 15. For instance  1231231231234585.1111 will be stored as 1,231,231,231,234,590.00.
I am using the expression "TRIM(cast((columnNmae(FORMAT '-Z(17)9.99')) as char(100)))" to  pull the data in the FastExport script but after exporting the data the output comes as "1231231231234585.11"instead of the rounded value stored in table i.e 1,231,231,231,234,590.00
Also if the size of the column is more than 17 in this case the data is getting filtered out.
Can anyone suggest any workaround for this scenario?

Indranil Roy

I thinking use a FOR EACH statment, but I didn't find anything about it.

 

How can I do this without manually change the date?

Hi guys,
I would like to know how read consistency is managed by teradata Fast Export.When it tries to read data from the database does it automatically request for rows on the table before the export process starts.Is there any special variable that needs to be used to maintain read consistency?I do find something like LOCKING modifier in the FastExport  reference guide but the usage is not clear?

Installing Teradata ODBC on AIX

Hi,
I am in need of installing Teradata ODBC on AIX 7.1.
I have downloaded the AIX Teradata ODBC file.  According to it's read file:

Prior to installing the "ODBC Driver for Teradata", the TTU dependency products that are listed
in section 3.3 must be installed first and in the order listed below.
TTU Products
============
1. Shared common components for Internationalization for Teradata (tdicu)
2. Teradata GSS client package (TeraGSS_aix_power)
It appears that both of the dependencies can be installed as part of the Teradata Tools and Utilities (TTU) package.  I have only be able to locate the Windows TTU download.  It's readme seems to offer hope that the Windows TTU can install the necessary packages for AIX but it's installation .exe files are DOS excutables:

TTUExpress_Windows.15.10.05.readme.txt
----------------------------

The 15.10.05 release now supports installing TTU products in any location for all OSes (Windows, OS X and UNIX).
I remain confused.  How do I download and install the required components for the ODBC AIX driver?
Many thanks,
-- John

I've got 2 installs of SQL Assistant, and neither are highlighting the error line when running queries, and I'm using the .Net connector.  One of them is the latest version, and a clean install on a new PC.

 

A coworker has his working and he's on v14 or v15 I beleive.  Is there some setting that I should check to enable this feature?

Queries for Teradata Fast Export Utility

July 28, 2016, 10:16 pm

We need to offload huge volume of data from a Teradata table to a network attached filesystem using the FastExport Utility.

The database will be a standalone server while the Fastexport script will be executed from the edge node of a hadoop cluster.

The data will be offloaded into the local file system of the edge node of the cluster .I have the following concerns with respect to the above 

job:

 

  1. Do I need to install the FastExport utility on the database server or the edge node i.e from where the script will be executed?
  2. Performance Tuning:According to the FastExport reference documentation the maximum number of sessions will be same as the number of AMP.Is there any other ways to fine tune the export performance of FastExport?
  3. What should be the CPU and memory configuration of the edge node to get the maximum performance from the export?

I Roy

MLOAD APPLY WHERE condition which is not an equality

August 1, 2016, 8:35 am
$

I have a very simple working MLOAD and have a new requirement to block data from being INSERTED.  I see many examples where the WHERE of an APPLY statement is specified as equality (=) and am sure I've done that in the past successfully, but my new requirement is to skip based on 'not equal to'.
 
 
Layout of file:

.LAYOUT INFILE_LAYOUT;

.FIELD INP_STR * INTEGER ;

.FIELD INP_ITM * INTEGER ;

 

 

Current IMPORT statement

 

.IMPORT INFILE INSERTS

LAYOUT INFILE_LAYOUT

APPLY INSERT

;

 

 

I have attempted all these variations, and all cause all records to fail the "Apply conditions satisfied" 

 

0017 .IMPORT INFILE INSERTS

LAYOUT INFILE_LAYOUT

APPLY INSERT

WHERE INP_STR <> 10108

;

 

 

0017 .IMPORT INFILE INSERTS

LAYOUT INFILE_LAYOUT

APPLY INSERT

WHERE INP_STR <> '10108'

;

 

0017 .IMPORT INFILE INSERTS

LAYOUT INFILE_LAYOUT

APPLY INSERT

WHERE INP_STR ¬= 10108

;

 

0017 .IMPORT INFILE INSERTS

LAYOUT INFILE_LAYOUT

APPLY INSERT

WHERE INP_STR NOT IN (10108)

;

 

0017 .IMPORT INFILE INSERTS

LAYOUT INFILE_LAYOUT

APPLY INSERT

WHERE INP_STR < 10000

;

 

 

All the attempted filters skip all the records.  (I have not yet put data in the file for the entity to be filtered.)

 

. IMPORT 1 Total thus far

. ========= ==============

Candidate records considered:........ 4659129....... 4659129

Apply conditions satisfied:.......... 0....... 0

Candidate records not applied:....... 4659129....... 4659129

Candidate records rejected:.......... 0....... 0

 
I've confirmed the data is applicable to be satisfied by all the conditions I have applied.  Example data follows:

File-AID - Browse - T01.SEH.TD3

COMMAND ===>

TPT with JDBC to Kafka

I can get TPT working from the Teradata Utilities on Linux, but I have to write this massive script to specify each column name and data type.
I'm trying to get it working from Kafka's JDBC connector, so I can just tell it to pull in data from a table incrementally.
Is is possible to use JDBC with TPT?  Or do I just use JDBC with FastExport?  Is that as good as TPT in terms of speed?
Do I just need to specify TYPE=FASTEXPORT in the connection string?
 
thanks,
imran
