问题 I'm just new in the informatica and I want to set a data loading that will handle error checking.

I just want configure the loading that my session will fail if there is truncation happen from source to reception. 回答1: By default, when a value is truncated, a warning is logged. If you want to treat truncation as an

问题 I have a powercenter 9.1 installation on windows server 2008 R2. The repository is on the same box, hosted on sql server 2012. I have configured a new user (with sql server authentication) and have the repo db owned by that user. (it has the owner role) The core problem : I am not able to run a simple test workflow on this setup. Here's what I have been trying The windows firewall has been taken down now for about an hour or so. The repository service and integration service are running in

问题 I'm sure that this is a pretty vague question that is difficult to answer but I would be grateful for any general thoughts on the subject. Let me give you a quick background. A decade ago, we used to write data loads reading input flat files from legacy applications and load them into our Datamart. Originally, our load programs were written in VB6 and cursored through the flat file and for each record, performed this general process: 1) Look up the record. If found, update it 2) else insert

问题 I have developed an Informatica PowerDesigner 9.1 ETL Job which uses lookup and an update transform to detect if the target table has the the incoming rows from the source or not. I have set for the Update transform a condition IIF(ISNULL(target_table_surrogate_id), DD_INSERT, DD_REJECT) Now, when the incoming row is already in the target table, the row is rejected. Informatica writes these rejected rows into a .bad file. How to prevent this? Is there a way to determine that the rejected rows

问题 The data in the source table is as follows: - Empno Ename sal 101 Allen 1000 102 Alex 2000 103 Tom 1500 104 Cb 2100 I want the output to be as follows :- Empno Ename sal 101 Allen 0 102 Alex 1000 103 tom 2000 104 Cb 1500 Can you please tell me by using which transformation i can acheive the result. Also plz let me know the logic. 回答1: Add an expression transformation with two variable ports: PORT EXPRESSION in_sal N/A v_previous_sal v_current_sal v_current_sal in_sal out_sal v_previous_sal

问题 Input column1 11 12 13 14 Desired output Colmn1 column2 11 Null 12 11 13 12 I have added the ports in the order as below in expression, column1 - colmn1 V-count - V_count+1 column2 - iif(V_count=1,null,v_col) V_col - column1 Since I studied as like the order of ports matters the execution order.so I added the v_col at last. But for column2 1st position is null and the remaining values in column2 are as same as column1. Can anyone tell what should I have to do to get the expected result? 回答1:
