Informatica: Write data into multiple files based on State name

问题

I have table with a column called State. My requirement is to read data from the table and write it into multiple files based on State name. I'm using Informatica PowerCenter as ETL tool

回答1:

Create a mapping as below:

Source --> SQ (sort data state name)--> Expression --> Transaction Control --> Target

Expression: Create a variable port to store previous value of state and a output port flag.

flag = IIF(state = var_state,0,1)
var_state = state

In Transaction Control Transformation, use TC_COMMIT_BEFORE when Flag = 1

Add Filename port to Target and map state name as filename.

You can also do this using post shell command:

Output file --> Name of output file of Informatica.
$2 --> assume 2nd field is the statement. Replace it as per your file

    awk -F\| '{print>$2}' outputfile
