SQL_SELECTOR: TPT15105: Error 13 in finalizing the table schema definition - response (9) by ericsun2
Hi Steven,
Thanks for the reply. Let me clarify my question:
-
NET_ID defined as Decimal(38,0) in DDL, but what should I define in TPT file schema?
-
when
MaxDecimalDigits = 18MaxDecimalDigits = 18MaxDecimalDigits = 18: shall I use VARCHAR(18), VARCHAR(19), VARCHAR(20) or VARCHAR(38)? - when MaxDecimalDigits = 38: shall I use VARCHAR(38), VARCHAR(39) or VARCHAR(40)?
-
when
-
NET_NAME is defined as VARCHAR(300) CHAR SET UNICODE in DDL
- when in UTF-8: I should use VARCHAR(900)
- when in UTF-16: I should use VARCHAR(600)
- when in ASCII: I should use VARCHAR(300), right?
- NET_KEY is defined as Decimal(9,0) in DDL, shall I use VARCHAR(9), VARCHAR(10) or VARCHAR(11)?
- If I have NET_TRAFFIC_BYTES defined as BIGINT in DDL, shall I use VARCHAR(20), VARCHAR(21) or VARCHAR(22)?

Well, without seeing the entire script, what you have shown me is a Selector operator retrieving 2 DECIMAL columns and a VARCHAR. Therefore, your schema must match.

Multi-Value compression has increased the table size - response (21) by amit.saxena0782
Hi Dieter,
I proposed a MVC to my client for Teradata 12 Tables. As per the analysis, I got around 800 GB approx saving on 2.3 TB of tables giving table level and column level savings. After too much of investigation on MVC, Client has come up with a concern as below:
Concern: Some of these columns are derived from bases that can change e.g. pricing strategies, cost price changes, tax (vat).
If any of these bases change the profile of the data in the tables will change, which means that a totally new set of ‘ideal’ compression values would apply.
How often would the compression values be reviewed?
As per my understanding , If the column values are more volatile for derived columns then we do not suggest applying the compression
But if columns values are more duplicate and static then apply the compress to save the space. But on the whole , I am still confused that even if the columns are derived, but I somehow still got the savings for that table, around 30%-40 %.
Can you please advise , if there is a way, we can apply compression on tables with some some/all derived columns, as i can see much saving ..
Regards,
Amit

Temporal usage classic scenerio - forum topic by Qamar.Shahbaz
Hi
I need to track history of party addresses and created a temporal table for this.
CREATE MULTISET TABLE Employee_Addr_Hist (
Name varchar(100),
City varchar (100),
VT PERIOD(DATE) NOT NULL
)
PRIMARY INDEX(name);
insert into Employee_Addr_Hist (name,city, Validity) values ( 'John','London' ,period( date '2011-01-01', until_changed) );
Now today(2013-03-19) I received a new row from source saying 'John' moved to 'Paris' on '2012-01-01'.
If I use below Update, CURRENT_DATE is used to close previous record and open new. Which is wrong as John moved to Paris on 2012-01-01.
update Employee_Addr_Hist
set City = 'Paris'
where name = 'John'
and end(VT) is until_changed
Can anyone help me in this? I just need to use source date for closing old record and opening new using Temporal features.

Performance considerations during taking back up-- - forum topic by Nishant.Bhardwaj
Hi Experts,
Need Your suggestions among the 2 possible scenerio through which we can take the backupof a Huge table at production.
Scenerio 1-
Create table a_bkp as A with Data and Stats;
Scenerio 2-
First Create empty table as create table A_bkp as A with no data .
second Use the merge statement to copy the data from main table to _bkp table
Merge statement in place of normal INsert select ...
like -
Merge into _bkp
Using A
I had a discussion with one of my peer and he suggested to go with scernio 2 not with scenerio 1 as it scenerio 1 will run into spool issues at the production as table is really huge and MERGE dont take any Spool to process the record how ever Insert Select does.
As i am bit unsure ,Just wanted to check this up Experts..
Thanks in advance.

How to retrieve the Relative Record Number? - response (9) by wicik
Hi there...
I have very similar problem like friend from the very start of the post.
I'm pretty nobbish in this type of SQL so please try not to be rough for me :)
Well.. I have to convert numeric field to date, than count some upload data and group by table.
Numeric_column like 20121121133549 which is probably like YYYYMMDDHHMMSS
Other columns are acces_point_type and data_uplink.
My goal is to convert numeric to Date (without time HHMMSS), count data_uplink and group by acces_point_type.
Simple group by would not be that problem but whole idea of convert data and connect it with casted date format and group by this, is pretty dark magic for me.
Any help would be appreciated.
PS: Sorry for my terrible English :/

How to retrieve the Relative Record Number? - response (10) by wicik
Well...
Sounds stupid but I have helped myself with default select --> copy paste to excel --> sorting and numeric conversion to date via left and right functions (to split needed numbers and connecting it as a date) and by makeing a PivotChart from all of it.
It gave me pretty the same but not that pro as it should.
Still, any help would be welcome :)
I need to learn how to do it properly.

Hello Mahesh,
You need not manually do entries into history. Is there an error displayed while you are trying to import the History XML? You could check the error log by selecting Window-> Show View -> Other Windows -> Error Log.
Procedure to Import:
1) Click on Import History tool bar button from Teradata SQL History View.
2) Browse the History XML and in the source types select "History (*.xml)" and click on OK.
If still things are working, can you zip the XML file and attached it here.
Ramesh.
