Schema and Edit
schema

A schema is a row description, it defines the nature and number of
fields to be processed. The schema is either built-in or remotely stored
in the Repository. The Schema defined is then passed on to the ELT
Mapper to be included to the Insert SQL statement.

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: The schema is created and
stored locally for this component only. Related topic: see
Talend Studio User Guide.

Repository: The schema already exists
and is stored in the Repository, hence can be reused. Related topic: see

Talend Studio User
Guide.

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.
