    • enter the name of the context variable you want to use to run the analysis using context. followed by the variable name, or
    • press Ctrl + space to open the list of context variables created in the Profiling perspective and from which you can select a variable of your choice.

      This list will be empty until you define context variables in the Contexts view in the analysis editor.

    In this example, type context.where_clause in the Where box.

    • enter the name of the context variable you want to use to run the analysis using context. followed by the variable name, or
    • press Ctrl+Space to open the list of context variables.

    For further information about defining context variables, see Creating one or multiple contexts for the same analysis.
  4. In the Context Group Settings view, select from the list the context environment you want to use to run the analysis, prod for this example.

    All context environments you create in the Contexts view in the analysis editor or you import from the Talend Studio repository will be accessible from this list.
