I would like to know if you could help me out. I have a a file with 2 columns (TABLENAME and CLOB) and in the TABLENAME there are "Providers". I would like to know how to set them at number 5000 and then increment them, per provider. So if I have 5 providers per file, it would be 5000, 5001, 5002, 5003, 5004. This is a daily file so we will get a file everyday. So Day 2, the 1st provider must be 5005...

From your question it appears that you want to generate a surrogate key with 5000 as seed value. This can be done through surrogate key generator using state file property and increment by 1. Set generate from last highest value also

Source->Transformer Stage -> Target
In transformer use 2 stage variables. Use hash Partition in the source and select key field and select sort option only. STG1 -> if stg2= keyfield then 1 else 0
stg2 - keyfield
Then in filter put condition stg1=0

Simple:
Source --> Sort (key distance) --> RD (retains 1st occuance) --> Target

What are these terms used for in Datastage - Downstream and Upstream?

kamal

• Apr 22nd, 2016

We can interpret Upstream as some thing flowing up like extracting data from source systems(similarly like extracting water from well) and downstream as data flowing into (like water flowing into canal).

mohan

• May 17th, 2013

Upstream means data channel from source system to ETL.
there are verity of source system (RDBMS, Flat Files, XML, ODBC).this data is integrated by ETL.this is input to ETL.
same as upstream.

Downstream means data generated from ETL.

I have faced an interview question recently.

In database we are using Bulk Collect concept to load the bunch of records ata time.

How we will achieve the same process in Datastage ?

Can we use any paticular stage or any other methodology we can implement.

Can any one help me on this.

Thanks in advance.

Bulk collect is retrieving multiple rows. With a single fetch.. Datastage is by default working in parellel and processing multiple rows at a time. As per my knowledge there is no such specific way to implement this
