In this blog post we will take a look at how to create an integer representation of the date of 30 days ago. For that reason I have created one job and two transformations, given that in pentaho every step is … I am new in PDI (passing from SSIS) and I am having some troubles by handling the variables issue. (I could take a crack at coding this up however I wanted to make sure that no one is currently working on this and that this would be a feature you'd consider including) Before running the job I go to Spoon and set the variable through the Edit / Set Environment Variable menu.

I have a transform 3-steps: Table input-select values-set variables that gets the row count of a table and set the field and variable to Row_Count and ROWCOUNT. Variable Scope type : 1.Valid in the virtual machine: the complete virtual machine will know about this variable. It accepts one (and only one) row of data to set the value of a variable. I have two transformations in the job. Values for Kettle environment variables set in the Pentaho MapReduce window override the Kettle environment variable values in the kettle.properties file. Variable: “ Variables can be used throughout Pentaho Data Integration, including in transformation steps and job entries. On some occasions you might have to set a variable value dynamically in a job so that you can pass it on to the Execute SQL Script job entry in example.
