Schema and Edit
Schema
|
A schema is a row description, it defines the number of fields to
be processed and passed on to the next component. The schema is
either Built-in or stored remotely
in the Repository.
Since version 5.6, both the Built-In mode and the Repository mode are
available in any of the Talend solutions.
Click Edit schema to make changes to the schema. If the
current schema is of the Repository type, three options are
available:
-
View schema: choose this option to view the
schema only.
-
Change to built-in property: choose this option
to change the schema to Built-in for local
changes.
-
Update repository connection: choose this option to change
the schema stored in the repository and decide whether to propagate the changes to
all the Jobs upon completion. If you just want to propagate the changes to the
current Job, you can select No upon completion and
choose this schema metadata again in the [Repository
Content] window.

Built-in: No property data stored

Global Variables
|
FILENAME_PATH: the path of the input file. This is an
After variable and it returns a string.
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.
