Global Variables

ERROR_MESSAGE: the error message generated by the component when an error occurs. This is an After variable and it returns a string. This variable functions only if the Die on error check box is cleared, if the component has this check box.

A Flow variable functions during the execution of a component while an After variable functions after the execution of the component.

To fill up a field or expression with a variable, press Ctrl + Space to access the variable list and choose the variable to use from it.

For further information about variables, see Talend Studio User Guide.

You can use tFileOutputDelimited to create the CSV files to be used. If so, bear the following configuration in mind:
  • Line separator: "\n"

  • Field separator: ","

  • Do not include headers.

  • File encoding: UTF-8.
