Precision loss during expression evaluation - data type issue? - forum topic by tstrick4
Hi, when I execute the following SQL
sel doc_id , prd_id , prd_cmn_name , net_quant , mvt_gravity , cast(net_quant*42*(mvt_gravity*8.338426855)-0.0101578 as DECIMAL(19,13)) from monroe_prd.movements
I am getting the following error:
SELECT Failed 2614: Precision loss during expression evaluation
Relevant table DDL is below
CREATE SET TABLE PRD.MOVEMENTS
(
DOC_ID DECIMAL(12,0) TITLE 'SRA Document ID',
PRD_ID CHAR(4) CHARACTER SET LATIN NOT CASESPECIFIC TITLE 'Product Code',
PRD_CMN_NAME VARCHAR(30) CHARACTER SET LATIN NOT CASESPECIFIC TITLE 'Product Name',
NET_QUANT DECIMAL(9,2) TITLE 'Net Quantity',
GROSS_QUANT DECIMAL(9,2) TITLE 'Gross Quantity',
MVT_GRAVITY DECIMAL(7,6) TITLE 'Gravity Spec',
MVT_API DECIMAL(10,7) TITLE 'Movement API',
CREATEDATETIME TIMESTAMP(0) TITLE 'CreateDate',
UPDATEDATETIME TIMESTAMP(0) TITLE 'UpdateDate')
UNIQUE PRIMARY INDEX ( DOC_ID ,DOC_NUM )
INDEX ( PRD_ID ,MVT_DATE );After reviewing the Messages manual, I have tried casting the result as 'FLOAT' and many other combinations of DECIMAL(m,n) and get the same error. I did the equation in a graphing calculator for a specific row and came up with a DECIMAL(19,13) answer, which is why i've been trying to cast as that data type. Ultimately I'd like to round the answer to 4 decimal places, but I have not yet gotten to that point.
Thanks in advance for any ideas that you have

Precision loss during expression evaluation - data type issue? - response (1) by VandeBergB
The 2614 error says that the result is too small. I plugged some literals your cast stmt, and got the same errors. When i force the order of operations and limit the values to four decimal places (you said you wanted to round to four places) it works.
Not sure if you want this evaluated left to right, but ...
SELECT 123456.33*42*(1.888333*8.338426855)-0.0101578
generates a 2614 error, casting that as float generates the error as well.
SELECT CAST(123456.3333*((42.0000*(1.8883*8.998))- 0.01015) AS FLOAT)
extending the integer of 42 to 42.0000 and limiting the other values to four decimal places returns a result....
SELECT CAST(123456.3333*((42.0000*(1.8883*8.338))- 0.0101578) AS FLOAT)
interesting conundrum...
SELECT CAST((123456.3333*42*1.8883*8.3384269) - .0101578 AS FLOAT)
the last row works as well.
What does your data profile look like, for the columns involved in the calculation?

In Viewpoint, which monitors both our prod and stage systems, I can right-click Export the Ruleset in Prod and save it to my machine. However, when I attempt to import that saved file is when I receive the error.

#Records estimation for Derived tables. " Too many rows" error - forum topic by mjasrotia
HI All,
We are facing a very frustrating problem in our reporting warehouse. We have given an adhoc BO universe to the business users. Users make their choices and execute the reports. Some of the metrics are derived using derived tables. If we have a static query we can always have the stats collected on the joined tables and the optimiser will have the high confidence records estimation and we can still control it somehow analysing the used filters. Now the problem we are facing is that since we can not collect stats on the derived tables so the optimiser is estimating records counts in millions which in turns fails the DBA set criteria in terms of the maximum records allowed hence we are getting "Too Many Rows" error and the queries are not executing.
Does anybody else faced the same issue. If yes how do we go about resloving this. Is it really suggestible to put a limit on the no of rows rather than on the time taken ?
Please suggest
Thanks
Manik

Data labs - Default permissions - forum topic by doneill@westpac.com.au
Our Production Teradata environment consists of several business silos across the organisation, each silo comprised of it's own set of databases and permissions. We're setting up datalabs in order to allow users access across these silos. These Datalab users will have read access across multiple silos.
A user created a view of a production table in a Data lab. On executing "Sel * from <viewname>, they received a "An owner referenced by user does not have SELECT WITH GRANT OPTION".
There are at least two possible solutions available:
1. I "grant sel on <prod DB> to <Datalab DB> with grant option" , or
2. I grant it "ALL <Datalab Parent DB>" (under which all our Datalabs reside
So my question is "Is there a best practice method for this scenario when using Datalabs

How to load EBCDIC file to db using TPT? - response (3) by Marcus1
I'm not using a mainframe.
I need to load a given EBCDIC file into Teradata on a network attached client. The EBCDIC file does not contain any packed columns, but does have columns with signed values.
I'm using TPT V13.10 on my TD notebook (or on TD VM Linux) and my test db is a remote TD 14.00 VM.
If it's not possible with TPT how about ML or FL?

what does UTY8709 mean in fastexport. - forum topic by robertskin
Hi, Guys
I am using fastexport to export my db result, but from the logs, there are some logs show like:
**** 18:42:33 UTY8722 234664 total records written to output file.
which means the records is write to the output file, but there are some logs show like:
**** 18:38:07 UTY8709 Restart in progress, processing for this FastExport task
has already been completed.
which seems like there is something wrong with the export and i have checked that there is no records there.
Could anyone tell me what does the message UTY8709 mean? or any clue is appreciated.

Perfect Query Timings needs to be captured - response (1) by VandeBergB
The starttime column in the dbc.dbqlogtbl table is when the query started. FirstRespTime is when the query was completed and the first row of the resultset was returned to the user/application.
Your query, depending upon what other fields you need from dbqlogtbl will look something like this...
SELECT (FIRSTSTEPTIME - Starttime) MINUTE TO SECOND AS ELAPSED FROM dbc.dbqlogtbl
