To call a different job within a job you are developing, you can use the tRunJob component. This
component allows you to execute another job as a subjob within a parent job. To pass the
parameters to the job you want to call, you can use the context parameters. Context parameters are
variables that can store values that can be changed at runtime or between different contexts. You can
define context parameters in the Contexts tab of your job and assign them values for each context.
You can also pass context parameters from the parent job to the child job by using the Context Param
tab of the tRunJob component. This way, you can parameterize the properties or expressions of the
child job with the values from the parent job.
You do not need to use a file, command line options, or Java function parameters to pass parameters
to a different job. These methods are not supported by Talend Studio and may cause errors or
unexpected results. Reference: Talend Open Studio: Open-source ETL and Free Data Integration |
