So here is were Looping is required tp we take a variable and increment the value. I can't seem to get variables to change after i initially set them. 1.Define variables in job properties section 2.Define variables in tranformation properties section 3.Configure job/transformation executor step. Before running the job I go to Spoon and set the variable through the Edit / Set Environment Variable menu. I would like to perform this: From a sql select query I would like to save the result into a variable. Variable Scope type : 1.Valid in the virtual machine: the complete virtual machine will know about this variable. Consider the job below which has two transformation embedded in it. Execution in Pentaho 7.1 => kitchen.sh -file=master.kjb -level=debug. If the variable name is not set or the variable name is not specified, this method simply returns the default value. If not, it convert the variable value to a boolean. 2020/05/20 09:48:01 - master - Start of job execution 2020/05/20 09:48:01 - master - Starting entry [Set variables (Optional)] 2020/05/20 09:48:01 - master - … I have two transformations in the job. To get system values, including command line arguments, use the Get System Info step.

The expectation is to pass the value(in this batch_id) to another transformation called test_pdi. Setting a variable value dynamically in a Pentaho Data Integration job. Pentaho Data Integration - Kettle; PDI-19029; PDI Pentaho Reporting Output step ${Internal.Entry.Current.Directory} variable gets set to empty The first tables uses a SQL query and the resulting column is passed to the set variables step. loadXML public void loadXML(Node entrynode, List databases, List slaveServers, Repository rep) throws KettleXMLException Description copied from interface: JobEntryInterface This method is called by PDI whenever a job entry needs to read its settings from XML.
