Transpose and Concatenating Values - response (3) by Qaisar Aftab Kiani
You need to write the recursive query.
I haven't tested this SQL, but I hope it will work for you
WITH RECURSIVE LOOKUP(ID,VALUE,LVL) AS ( SELECT ID, MIN(VALUE(VARCHAR(1000))) AS VALUE,1 as LVL FROM table1 GROUP BY 1 UNION ALL SELECT b.ID,trim(a.VALUE) || ';' || trim( b.VALUE), LVL+1 FROM table1 a INNER JOIN LOOKUP b ON a.ID = b.ID AND a.VALUE > b.VALUE ) SELECT ID, VALUE, LVL FROM LOOKUP QUALIFY RANK() OVER(PARTITION BY id ORDER BY VALUE DESC) = 1;

Recursive Query Issue - response (6) by Qaisar Aftab Kiani
I have written something very quickly but haven't tested it. Probably some minor tweaks would do the trick.
CREATE SET TABLE foo ( Number_id integer, FF_String VARCHAR(100), STRGY_TC VARCHAR(100), ) PRIMARY INDEX ( Number_id ); INSERT INTO FOO VALUES (135, 'DD_B_SEG', '48647_002'); INSERT INTO FOO VALUES (127, 'ATM_B_NP', '48557_001|48557_002|48557_003|48558_004|48558_005|485 5 8_006|48558_007|48558_008'); With Recursive LOOKUP (Number_id, FF_String, STRGY_TC ) As ( Select Number_id , FF_String , substr(STRGY_TC, 1, index(STRGY_TC,'|')-1) || '' || substr(STRGY_TC, index(STRGY_TC,'|') +1, character_length(STRGY_TC)) as STRGY_TC From foo root union all Select direct.Number_id , direct.FF_String , substr(direct.STRGY_TC, index(direct.STRGY_TC,'|')+1,100 ) as STRGY_TC From LOOKUP direct where index(direct.STRGY_TC,'|') >0) select b.Number_id , b.FF_String , TRIM(substr(b.STRGY_TC, 1, index(b.STRGY_TC, '_')-1)) AS Strgy , TRIM(substr(b.STRGY_TC, index(b.STRGY_TC, '_')+1,character_length(b.STRGY_TC))) AS Test from LOOKUP b where index(b.STRGY_TC,'|')=0

Fast Export and MLoad - response (5) by islanderman
Hoping someone can give me guidance. Currently we have large loads of data being inserted to Teradata via a perl script from Linux RedHat. The insertion is line by line so it takes hours to load. I was able to install tdicu, tdodbc, TeraGSS by downloading the tar files from this site. I was able to configure DBD::ODBC to connect to the Teradata DB and the insertion works fine. I've been told to use JDBC for Mload or Bteq or Fastload, but I'm not familiar enough with Java. I've been told to work with TPT 14, which is part of TTU, but I don't know how to get the software for Linux.
First of all, I assume that all of the Mload/Fastload/Bteq is all part of the TTU package, is that correct?
If I happen to get the software can I use perl to execute the Mload/Fastload/Bteq script?
Any help would be appreciated.

Fast Export and MLoad - response (6) by feinholz
If you are going to be using our load/unload tools for the first time, you should use TPT. It is the suite of load/unload tools going forward.
TPT is part of TTU and can be found in the same media as the rest of the software.

TPT error in loading from an external file - response (3) by simplesim092
Does any one has resolution for this..I am facing teh same issue as point 2.. as above and There is no EOF

TPT error in loading from an external file - response (4) by feinholz
I would imagine all files have an EOF.
Every record should also have EOR.
(We are fixing the code so that we will treat EOF as EOR on the last record, but that fix is not out yet. Thus, add an EOR to your last record.)

BTEQ Batch mode, commands / SQL run from shared server. - forum topic by istari
Windows 7: BTEQ 13 and 14
Calling a batch file from end users machine shortcut, target is \\server\folder\file.bat, start in %temp% to prevent CMD prompt errors.
bteq < \\server\folder\commands.txt
commands.txt contains
login info
.EXPORT REPORT FILE=\\server\folder\output.csv
.RUN file \\server\folder\sql.txt
Problem: When shortcut is run, it outputs bteq 0<\\server\folder\commands.txt and breaks. (note the zero before the input)
in BTEQ, when just running the command straight from there bteq < \\server\folder\commands.txt everything works.
When everything is local, and shortcut points to a local batch file, with local commands, login, and sql files, it runs.
Thoughts/Suggstions?
Thank you.

Using a PPI column in PI - response (3) by VandeBergB
if your downstream queries don't access the new composite PI you'll have full table scans. what defines the most common access path to the table with colA and colB? You've got an extreme case of 80% skew and 7% skew. I'd suspect that your initial PI doesn't define the most common access path because of the data clustering in colA.
build some test cases and see what the explains look like

TPT Data load from csv file - response (1) by simplesim092
This esolution has been done..My data in csv file had same symbol as i m using as delimiter..So I added
in the DEFINE OPERATOR FILE_READER
TYPE DATACONNECTOR PRODUCER
SCHEMA TGT_TABLE_SCHEMA
ATTRIBUTES
(
VARCHAR OpenQuoteMark = '"',
VARCHAR CloseQuoteMark = '"',
VARCHAR Format = 'Delimited',
VARCHAR OpenMode = 'Read',
It worked well and data got loaded....!!! :-)
↧
Fastload does not support or can ignore quoting character as part of data. The csv file while saving by different application adds additinal quotes for their application differently.
I will suggest in this case to use a shell/perl script to
1. change the quoted character '"'
2. change the two double quote character which represent a single quote in data to one.
the data:
"D9F570F6-538B-4795-98A4-021D99C03576"|"""BUREAU,TARIFICATION"""
becomes:
*D9F570F6-538B-4795-98A4-021D99C03576*|*"BUREAU,TARIFICATION"*
then use fastload command as:
SET RECORD VARTEXT DELIMITER '|' QUOTE YES '*';
