SQ->exp->filter->target

In expression we need to calculate sequence number then filter records in filter transformation as column>=50 and column

Naveen

Use SQ --> EXP --> RANK --> TGT

In EXP initialize v_count=v_count+1
In Rank Txn, rank on v_count and select BOTTOM 100.

I think, this will work.

Guys I have got the answer for which I asked..here you go

This can be handled by using the file list in informatica. If we have 5 files in different locations on the server and we need to load in to single target table. In session properties we need to change the file type as Indirect.
(Direct if the source file contains the source data. Choose Indirect if the source file contains a list of files.
When you select Indirect, the PowerCenter Server finds the file list then reads each listed file when it executes the session.)
am taking a notepad and giving following paths and file
names in this notepad and saving this notepad as
emp_source.txt in the directory /ftp_data/webrep/

/ftp_data/webrep/SrcFiles/abc.txt
/ftp_data/webrep/bcd.txt
/ftp_data/webrep/srcfilesforsessions/xyz.txt
/ftp_data/webrep/SrcFiles/uvw.txt
/ftp_data/webrep/pqr.txt

In session properties i give /ftp_data/webrep/ in the
directory path and file name as emp_source.txt and file type as Indirect.

Anurag

• Nov 27th, 2017

You should use a indirect file (which contain path and name of all the 5 files) as source. Transformation depends on the business logic.

When we have the same structured flat files, why don't simply use UNION make them a single file and then load to target instead of such complication? or UNION doesn't work on flat files?

What Md.Rehman is trying to say is catagorizing the SCD which are the Slowly Changing Dimensions which are used to maintain historical data.

Dimension:A dimension is an organized hierarchy of categories, known as levels, that describes data in data warehouse fact tables

The various types of dimensions are :

1) Shared and Private Dimensions: Describes the basic differences between shared and private dimensions and their uses

2) Regular Dimensions: Provides information about regular dimensions and their variations

3) Parent-Child Dimensions: Describes the creation of parent-child dimensions and identifies their advantages and restrictions

4) Data Mining Dimensions: Describes the creation of data mining dimensions and identifies advantages and restrictions to their use

5) Virtual Dimensions:Describes the creation of virtual dimensions and their advantages and restrictions

6) Dependent Dimensions: Describes the creation of dependent dimensions and identifies their advantages and restrictions

7) Write-Enabled Dimensions: Describes the creation of write-enabled dimensions and identifies their advantages and restrictions

1. You cannot perform DD_Delete unless you have update strategy.
2. While updating a record, ideally created date should not be changed. for that we definitely have to create two targets (insert and update)

We cannot use Update strategy in a pipeline when using joiner condition, because update strategy has property i.e treat row as which has insert,update,delete, which are processed at runtime, this limit joiner transformation to know exact properties values till runtime, and then proceed further.
