0 - 2 of 2 tags for flat file

I have the requirement, where for one of the client I need to incorporate the filename in Teradata table. Client has Teradata 13 machine. We have a fixed width source flat file and we are using TPT script in "TEXT" format. 

 

Hello,

How does TPUMP behaves if we have 2 rows with same UPI key in flat file?

Is there any method it choose order of data while executing tpump?

I have flat file with data as:

 

ID | Name

1 | A

1 | B
