Teradata TPT Load method
Posted: Thu Mar 17, 2011 4:14 am
Hi ,
I need to confirmation about a case where i am fetching data from Teradata table and loading data into same table through TPT stage in same job.
As of now , job is loading data without any misappropriation. What i understand TPT->Bulk->Load is fastLoad method. So it should create empty work table , load data in it , then append work table data in target(source) table , lastly drop work table.( At least this holds true in Tedata Enterprise stage).
Can anyone endorse above understanding for TPT stage? OR reading & loading data from/in same table in same job can be errornuous/risky?
Thanks in advance.
